Questions worth asking first

New here? Start with these.

What is RaceMetrics RC?

A performance-tracking app for RC car racers. We pull lap times and results from the major RC timing services — see Data Sources for the full list — so you can see your races, your driver profile, your achievements, and how you stack up, all in one place.

Do I need an account?

You can browse race results, driver profiles, and venue pages without one. Sign in to claim your transponder, save setups, get your own dashboard, and join Head-to-Head.

How do I install it as an app on my phone?

Open the site in your browser, tap the Share/menu icon, then Add to Home Screen. You get a full-screen app icon and offline support for cached pages — no app store.

I race at more than one club. What should I do?

Add every transponder ID you use under Account → My Garage. Transponder IDs are not globally unique, so without all of them, results from drivers at other clubs sharing your number can leak in (or yours can be missed).

I race with my kids. Do they need their own accounts?

No — add them as family members under Account → Family. They get their own driver identity, results and notifications, all held inside your account with no email or login of their own.

What is the "Complete your profile" checklist on the home page?

A four-step checklist that lights up the things still missing from your profile so features like My Results, setup analytics, and live notifications work properly. Each row links to the place that fixes it: Basic information (name, primary club, transponder), My Garage (a car linked to a club with a class set), First setup sheet (≥75% complete), Location (postcode for nearest-venue suggestions). A green tick = done, an amber warning = started but missing pieces (caption tells you exactly what), gray circle = not started. Once all four are green the card auto-hides; tap × to dismiss earlier.

I dismissed the checklist — how do I bring it back?

Visit /?force-checklist to render it on top of any state. Or, in DevTools → Application → Local Storage (under this site), remove the setupChecklistDismissed entry.

install_mobile Installing the App

RaceMetrics RC installs straight from your browser — there is no app store listing to find.

How do I install it on an iPhone or iPad?

Open the site in Safari, tap the Share button, then Add to Home Screen. Chrome and Firefox on iOS don't offer it — Apple only allows Safari to install web apps.

How do I install it on Android?

In Chrome, either tap Install App when we offer it, or open the browser menu (three dots) and choose Install app / Add to Home screen. Edge, Samsung Internet and Brave all work the same way.

There's no prompt — where did it go?

The menu always has an Install App entry, so start there. A prompt won't reappear if you dismissed it recently, and it never shows at all once the app is installed.

Do I need to install it to get notifications on an iPhone?

Yes. Apple only allows web push for apps added to the Home Screen, so on iOS notifications stay switched off until you install and open it from the icon. Android and desktop can enable them straight from the browser.

What does installing actually change?

You get your own icon, a full-screen app with no browser bar, and cached pages that still open when signal drops at the track. It is the same site and the same login — nothing to migrate.

Is it on the App Store or Google Play?

No — it's a web app you install from the browser, which is why updates land the moment we ship them with nothing to download. Uninstall it like any other app icon if you'd rather go back to a browser tab.

account_circle Account & Profile

How do I add my transponder ID?

Account → Profile → Transponder ID. Use the number from your timing transponder, not your driver number.

Can I add multiple transponders?

Yes — add each one under Account → My Garage and assign it to the right car. Set the most-used one as Primary.

How do I set my home venue?

Account → Profile → Home Venue. Used to filter your dashboard and surface meetings you care about on the home screen.

How do I add my car?

Account → My Garage → Add Car. Pick manufacturer + model and assign your transponder. While you're filling the form, pick a club / venue and the class you race in — both land when you click Save, and the modal flips into Edit mode so you can drop in a setup sheet immediately.

What's the difference between My Garage, My Clubs, and Favourite Clubs?

Old "My Cars" + "My Clubs/Events" tabs are now combined into My Garage. Each car card shows the venues you race that car at as chips (Stoke RCMCC · 13.5T) — tap a chip to edit the class or remove it. Unlinked clubs appears below cars only if you have a club row that's not yet linked to any car (used to nudge you to assign one). Favourite Clubs at the bottom is for clubs you follow for live results, not ones you race at — tap the heart on any club page to pin it.

What do the "Club required" and "Class required" warnings mean?

Amber warning chips on a car card mean it's missing data we use for filtering and stats. Club required: the car isn't linked to any venue — tap the chip to pick one. Class required: it's linked to a venue but no class is set for that venue — tap the chip to open the class dropdown. Both warnings also surface in the home-page checklist ("1 car needs a class" etc.) until fixed.

Can I delete my account?

Yes — Account → Privacy → Delete Account. We remove your profile and saved setups; your race results stay (they're part of public meeting data).

family_restroom Family

Racing with your kids? Add them under Account → Family and their racing lands in your account alongside your own.

What is a family member?

Someone you race with who doesn't have an account of their own — usually a child. They get a full driver identity (name, club, transponder, cars, setup sheets, badges), but you hold it: their results appear in your My Results and their notifications come to your devices. Add one under Account → Family → + Add Family Member.

Do they need an email address or a login?

No — that's the point of the feature. A family member has no email, no password and nothing to sign in to. Everything about them is reached through your account.

How many can I add?

Up to 10.

Do they need their own transponder ID?

It's optional but worth adding. With a transponder we match their races exactly the way we match yours; without one we fall back to matching their name at their club, which is less reliable. Head-to-Head needs one outright — a name-only member can't take part until you add it. Everyone in the family needs a different number: two people sharing one would double every notification and clash on rival picks.

Where do their results show up?

On My Results, a row of name chips appears above your stats as soon as you have one family member. Tap a name to switch the whole page — stats, race history, report cards — to that person. Your chip carries a person, theirs a child_care.

Who gets their notifications?

You do — there is no inbox of theirs to log in to. Anything about a family member lands in your bell and on your devices with their name on a badge, so a mixed family inbox stays readable. Each member has their own set of toggles under Account → Family, so you can have race results for one child and nothing for another.

Can they play Head-to-Head?

Yes, once they have a transponder ID. The Head-to-Head section on the meeting page grows the same name-chip switcher — pick who you're choosing a rival for, then pick the rival. Each person's picks, eligibility and lock state are their own.

Can other people see my children?

Not by default. Family members are hidden from the public driver lists, driver search and the setup-sheet directory. The Public switch on a member's row opts that one person into the public driver lists if you'd like them findable. Setup sheets stay private either way — that toggle never shares them.

How do I say which car belongs to whom?

Once you have a family member, the Add / Edit Car form in My Garage grows a Whose car is this? dropdown. Set the owner when you add the car, or change it later to move a car between people.

Their name is spelled differently in some results — can I fix that?

Yes. Open Edit on their row (or the name-variants button on it) and add the other spellings under Name Variants. We suggest names already recorded against their transponder plus close matches on their name — the same tool as your own name variants.

What happens if I remove a family member?

Their identity and everything under it goes — cars, setup sheets, name variants, badges, preferences — along with the notifications about them sitting in your inbox. Their race results stay, because those are public timing data about a race rather than account data. There's no undo, so remove carefully.

Can they take over their own account when they're older?

Not yet. Handing an identity across to a real email address is on the list but isn't built, so for now the racing history stays under your account. Tell us if you need it and we'll prioritise it.

badge Driver Profile

The public driver page at /driver/:transponder.

What's the difference between this and My Results?

Driver profile is the public view of any driver — anyone with the URL can see it. My Results is your private dashboard with extra tools (Driver Report Cards, performance analysis) that only you see.

Why are some of my races missing?

We match races by transponder ID + driver name. If your name was entered differently in a race result (typo or abbreviation), that race won't be matched. Tell us and we'll look into it.

How is my Driver Category calculated?

We average your lap-time consistency over your last 30 races and add a small bonus once you've passed 5 wins. The result tiers as: Sunday Driver (<60), Hot Lapper (60–84), Speed Demon (85+).

What badges can I earn and how?

Badges are computed from your race history — no manual claiming. Open any driver profile and click the info next to Achievements to see which you've earned. Full list:

• emoji_events Final Winner — win any final.
• workspace_premium Final Podium — top 3 in any final.
• flag_circle A Final Race — race in an A Final.
• military_tech A Final Winner — win an A Final.
• looks_one Pole Position — qualify 1st in any qualifying race.
• bolt Fastest Lap — set the fastest lap of a race.
• task_alt Consistent (bronze) — ≥80% average consistency over the last 10 races.
• verified Elite Consistency (silver) — ≥90% over the last 10.
• auto_awesome Untouchable (gold) — ≥95% over the last 10.
• event_repeat Regular Racer — attended 3+ meetings in the last 4 weeks.
• speed Top Qualifier — average qualifying position ≤ 3 (after 5+ qualifying races).
• auto_awesome_motion Clean Sweep — top qualifier and A Final winner at the same meeting.
• rocket_launch Dominant Drive — win a final by 1+ lap or 5+ seconds over P2.
• swords Head-to-Head Winner — pick a nemesis and beat them at any meeting.

Why hasn't my Consistency badge upgraded?

Consistency is averaged over your last 10 races, so it shifts gradually. The tiers are Consistent (≥80%), Elite Consistency (≥90%), Untouchable (≥95%). One bad result can drag the average down even if individual rounds were tidy.

I haven't raced in a while — why did my Regular Racer badge disappear?

Regular Racer requires 3+ meetings in the last 4 weeks, so it lapses if you skip too many. It comes back automatically next time you hit the threshold.

Why does Recent Meetings only show 3?

Tap Show more at the bottom of the list — it expands to the full 10 we cache for the profile.

Can I share my profile?

Yes — tap the menu (⋮) in the profile header → Share. The dialog shows a QR code, the public URL, and a tap-to-copy button so you can hand it off any way you like.

bar_chart My Results

Your private dashboard at /my-results.

Why is a race I just finished not showing yet?

We poll each supported timing service continuously. New races usually appear within 5–15 minutes of being posted upstream. If it's been longer, tell us the meeting and we'll check the scraper.

How is consistency calculated?

We take the standard deviation of your lap times divided by the average (the coefficient of variation), then map it to a 0–100% scale. Higher = more consistent. A clean run with all laps in a tight band scores higher than a run with one outlier.

Your first lap is left out by default, because a standing start is not racing pace. It runs over a second slower than the rest of the run at every venue we measured, and far more where the grid sits back from the timing loop. You can put it back with the Drop start lap chip wherever consistency is shown.

One thing worth knowing: consistency is a percentage of your own average lap, so a shorter track scores lower than a long one for exactly the same wobble.

What's the difference between Best Lap and Best 3 Avg?

Best Lap is your single fastest lap. Best 3 Avg is the average of your three fastest consecutive laps — a better measure of pace you can sustain.

What does the Lap Spread column (and the coloured Δ on the Consistency tab) mean?

Lap Spread shows how repeatable your peak pace was — the gap between your single best lap and your 5th-best lap (3rd-best in short races). Because it only looks at your fastest laps, a crash or a marshalled lap never affects it, which makes it different from the Consistency % above (that one uses every lap). Smaller is better. The colour is a band relative to your own best lap, calibrated from real race data: green = within 2% (metronomic), amber = 2–4% (typical), red = over 4% (peak pace tailed off). It shows as the Lap Spread column on the race-results table and as the Δ line on the mobile Consistency tab.

What's the Driver Report Card?

A shareable image summarising your performance at a single meeting (or your all-time stats). Click Driver Report Card in My Results to choose options and generate one.

How do I filter the Race History?

Use the All / Qualifying / Final pills above the timeline, plus the venue dropdown. The count line tells you how many of your total races match the current filter.

Why are race types showing as 'qualifying' or 'final' instead of A/B/C?

The pill row filters by race type. The badge on each race card shows the specific final (A/B/C) or qualifying round number.

sports_kabaddi Head-to-Head

The weekly rivalry game at /head-to-head-leaderboard.

How does Head-to-Head work?

Pick a rival before each meeting. If they pick you back, that's a mutual rivalry worth more points. You both race the meeting, then results unlock the morning after with points awarded.

How are points calculated?

+30 for a win, +10 for a loss when you beat them straight up. +100 / +50 for mutual rivalries. Skill-based bonuses on top reward beating someone better than you.

What's a mutual rivalry?

When two drivers pick each other before the deadline. Doubles the stakes — the win is worth a lot more, but so is the loss.

Why can't I pick a rival yet?

Selections are open in a fixed window before each meeting (typically Sunday → Friday). The banner on /head-to-head-leaderboard shows when the next window opens.

tune Setup Sheets

Save, share, and compare your car setups.

What's a setup sheet?

Your car's settings — gearing, suspension, tyres, geometry, electronics — saved in a structured form so you can compare, share, and roll back when something goes wrong.

How do I create one?

Account → My Garage → tap a car → Setup Sheets → New Setup. We save versions automatically, so you can always restore an earlier setup.

How do I share my setup?

From the setup edit page → Share. Generates a public link any racer can read.

Who can see my setups?

Only setups you've explicitly shared. Drafts and private versions stay tied to your account.

What does 'Detailed' mean in the sort filter?

Sorts the All Drivers list by how many fields each driver has filled in for their latest setup version — most-detailed first. Useful when you're looking for a thorough reference.

Can I see whether a setup change actually helped?

Yes. Open a car and choose Analytics (or go to /setup-sheets?tab=analytics). Each setup version gets a card with its best lap, average and consistency, and below that a version-by-version comparison, a meeting-by-meeting breakdown, and a Setup Change Impact card for every change you made, marked Improved, Declined or Neutral. Analytics is an Advanced-mode feature.

What are the Lap Spread and Every Lap charts?

Lap Spread by Setup puts one box per setup version, oldest first, covering every lap you drove on it. It answers the question the version cards cannot: whether a change made the car steadier, or just handed you one lucky lap. Every Lap, by Setup plots all of those laps on a calendar, coloured by version, so a setup change shows as the whole cloud moving. Both follow the race-type filter above them. See Reading the Charts.

Why does my average lap barely move when I drop the start lap?

Because the version card’s Avg Lap is the average of each race’s best lap, not the average of every lap. Your standing start is never your best lap, so taking it out changes almost nothing there. Consistency is where you will see the difference.

Can I export a setup as a PDF?

Yes — open any setup edit page and tap Export PDF.

settings Gearing Calculator

Work out FDR and rollout, and see what a gear change will actually do before you cut a run.

What does the gearing calculator do?

Enter pinion, spur, internal ratio and tyre diameter, and it gives you the spur:pinion ratio, the final drive ratio (FDR) and your rollout. Find it at My Garage → Gearing Calculator.

How do I compare two gear choices?

Fill in Current and New side by side — the calculator shows the percentage change between them as you type. On a phone the two sit behind Current and New tabs.

What does the percentage change actually mean?

Positive and red means more load on the motor: better acceleration, lower top speed. Negative and green means less load: more top speed, less punch out of the corners.

What is rollout?

How far the car travels per rotation of the motor, in millimetres — tyre diameter times pi, divided by the FDR. It only appears once you enter a tyre diameter, which is why that field is optional.

I don't know my internal ratio — can it help?

Pick your class from the Preset dropdown and it fills in a sensible internal ratio, tyre size and starting gears: 1/10 on-road modified and stock 17.5T, 1/10 2WD and 4WD buggy, 1/8 buggy, and 1/12 on-road. Use 1.0 if you're running direct drive.

Does it remember my numbers?

Yes — in whichever browser you used, with no account needed. Reset puts every field back to the defaults.

checklist Reminders & Ideas

Your garage notebook: setup ideas to try on the car, and reminders that land on your phone at the time you choose. Ideas also show up in the notes after each run, so you can tick one off the moment you know how it went.

What is Reminders & Ideas?

Two lists in one place, under My Garage → Reminders & Ideas. Ideas are setup things you want to try — softer springs, a different pinion, thicker diff oil. To do holds reminders: things to do at a set date and time, like charging the batteries the night before a meeting. It is in Basic mode, and it is free.

What is the difference between an idea and a reminder?

A reminder has a date and time and sends you a notification when it is due. An idea is just a line of text with no time — it waits in the list until you try it. When you want a nudge to actually do one, tap Remind me on the idea (the alarm-clock button) to turn it into a reminder.

How do I add an idea?

On the Ideas tab, type it in the box at the top and tap Add idea, or press Enter. The box clears and stays ready, so you can jot down several in a row.

How do I set a reminder?

On the To do tab, type what you need to do in the box at the top. As soon as you start typing, the time options appear with In 1 hour already picked. Tap another quick pick — Tonight 7pm, Tomorrow 8am or Saturday 8am — or tap Pick a time to choose any date and time (tap it again to hide the picker). Tap Notes or car to add details or link a car, then Add reminder. Times are in your phone’s own time zone. The ⓘ next to the tabs explains how reminders reach you.

How do I get a reminder on my phone?

Every reminder arrives in your notifications at the time you set. To get it on your lock screen as well, install the app and turn on push under Account → Preferences → Notifications, and make sure Reminders is switched on there. Quiet hours do not hold a reminder back: you picked the time, so it arrives on time.

How do I edit or move something?

Tap it — it opens for editing right where it is in the list. Change the text, or for a reminder the car or the time, and tap Save. Moving a reminder that has already gone off sets it up to go off again at the new time.

A reminder is overdue — can I snooze it?

Yes. An overdue reminder shows OVERDUE in amber and a +1 hr button. Tap it to push the reminder an hour from now, and it will go off again then.

How do I delete an idea or reminder?

Swipe the item to the left and tap the red Delete that slides out — this works on ideas, on everything in What you’ve tried, and on reminders. You can also tap an item to open it and tap Delete there. Either way it disappears straight away and an Undo button shows for a few seconds, in case it was a mis-tap.

I have tried an idea — now what?

Tick it. It moves to What you’ve tried and asks How did it go? — answer Better, No change or Worse. Everything you have tried stays on the Ideas tab as your logbook, with its result, so the next time you think about softer springs you can see you already tried them and what happened. Tap a result to change it, or tick the idea again to move it back to ideas to try.

Can I tick an idea off from a race or practice run?

Yes — that is usually the quickest way. The notes you add to a race or practice run ask Did you try any of these? and list your open ideas. Pick Better, No change or Worse and save: the idea is ticked off with that result, and in What you’ve tried it says which run it was, like Tried in a race · Sat 20 Sept.

What do the numbers on the tabs and in the menu mean?

How many things are still open: on the tabs, reminders not yet done and ideas not yet tried; in the menu next to Reminders & Ideas, the two added together. Done reminders and tried ideas are not counted.

Can I link something to a car?

When you set a reminder you can pick one of the cars in My Garage, and its name shows on the reminder. Deleting a car keeps your reminders; they just lose the car label.

Who can see my reminders and ideas?

Only you. They are private to your account — there is no public page, and nothing is shared with other drivers.

Is there a limit?

You can have up to 200 open reminders at once. Tick some off to add more. Ideas have no limit.

edit_note Notes after each run

Write down how the car felt while it is fresh: a score out of ten, a few words, and which of your ideas you tried.

How do I add notes to a race or practice run?

Tap Add notes on the race in My Results (it is the first button under each result), or open a run in Practice and tap Add notes — that works for runs from the Lap Timer and runs you imported from LapMonitor. The notes open in a panel: from the bottom on a phone, from the side on a bigger screen. Once a run has notes the button shows your score, like Notes 7/10, and a practice card shows the score next to its title. Notes are in Basic mode.

What does the score out of ten mean?

It is how the car handled, in your own judgement: 1 is undriveable, 10 is dialled in. Over a season it shows whether your setup changes are moving the car the right way. Tap the same number again to clear it.

What is the balance grid?

In Advanced mode the notes also have a balance grid, like the one in setup apps. There are six sliders: Entry, Mid and Exit of the corner, at low speed and at high speed. Push a slider up (+) if the front was the limit and the car pushed wide, and pull it down (−) if the rear was the limit and the car was loose. Each goes from −3 to +3, and 0 means neutral. Double-click a slider to centre it. In Basic mode the grid is hidden, but anything you already recorded is kept.

Why does it ask whether I tried my ideas?

Any ideas you have not tried yet are listed in the notes, with the ones for that car first. Pick Better, No change or Worse and the idea is ticked off with that result. It then moves to What you’ve tried, labelled with the race or practice run it was tried in. Clear the pick and save to put it back on your list.

What are the setup changes in the notes?

They are the setup sheet changes for that car since your previous race or practice run: which values changed and what they changed from. That includes values you edited on the current sheet without saving a new version, so a quick shock oil swap between rounds still shows. Changes are recorded from this update onwards; for older runs you only see the difference between two saved versions.

Who can see my run notes?

Only you. If you manage a family account, notes you write while viewing a child’s results are saved against that child.

Which car do the notes use?

For a practice run, the car it was saved with. For a race, the car whose transponder matches the one you raced with, or your primary car if none does. If you have more than one car, you can switch it in the Setup changes part of the notes, and the list of changes follows the car you pick.

Can I change or delete my notes?

Tap Notes on the run again — everything you saved is filled back in; change it and tap Save notes. Delete at the bottom removes the notes, and any idea you ticked off in them goes back onto your list of ideas to try.

timer Lap Timer & Practice Sessions

Time a practice session by tapping once a lap — or import the laps from LapMonitor — then read it back the way you read a race.

What is the Lap Timer for?

Practice, and any club night where there is no timing loop. The app only has data when a club runs a timing system a scraper can reach, so solo practice, open days and tracks without transponder timing produce nothing at all. The Lap Timer fills that gap. Set a session length, prop the phone on the rostrum, and tap once every time the car crosses the line.

Do I need an account?

Not to use it. The timer itself works signed out, and a session you time before signing in is held on your phone and offered for saving afterwards. Saving, your history, the trends, the comparison and the report card all need an account.

How do I set a session up?

Pick a car, a session length and a countdown. Choosing a car brings its club, venue and class with it, so the session files itself next to the right races later. If you manage a family member you can pick them first, and the session saves against their identity rather than yours. No car is fine either; you can add one afterwards.

Do I have to tap the screen for every lap?

No. Under Options you can choose how a lap is recorded. Sound listens for a sharp noise — a tongue-click, a clap, a shout — and works best through earphones, where the microphone is at your mouth rather than pointed at the track. Knock uses the phone's motion sensors, so a knock on whatever it is resting on records a lap. Remote takes a keypress, which is what the cheap Bluetooth camera shutters send; taped to the transmitter, one of those is the only option that never asks you to let go of it. The big panel stays live whichever you pick, so the screen is always there to fall back on.

Which one should I use?

A Bluetooth remote if you have one, because your hands stay where they are and it is the closest thing to pressing a button on a real timing box. Sound if you do not, especially with earphones in. Knock is the weakest of the three and worth being honest about: a knock hard enough for the phone to detect is also a knock a marshal, a gust or a dropped transmitter can deliver, so it suits a phone somewhere nothing else will touch it.

Why does it ask permission when I turn one on, and what happens to it after?

Browsers only grant a microphone or a motion sensor in response to something you deliberately did, so it has to ask on the click that switches the option on rather than later when the session starts. The microphone listens only between the green flag and the end of the session, plus while the Options panel is open so you can test it, and it is released entirely afterwards — not merely told to stop — so your phone's recording indicator goes out. Nothing is recorded, stored or sent anywhere: the only thing read is how loud each instant is.

It cannot hear me, or it records laps I did not ask for

There is a Sensitivity slider next to the option, and a meter above it that moves with whatever the phone is hearing or feeling. Open Options, make the noise you plan to use, and watch it: if the bar barely moves, turn sensitivity up or get the microphone closer to your mouth; if it is firing on the track rather than on you, turn it down. It works out the background level for itself and re-learns as a venue gets louder, so the number to chase is one where your click stands out from the room, not one that is simply high. It also refuses anything arriving too soon after the last lap, so a single knock cannot become four.

Which Bluetooth remote works?

The five-pound camera shutter remotes pair as a Bluetooth keyboard, and the app treats that keypress as a lap. What they send varies: on Android they usually send Enter, which works. On iOS many send only a volume keypress, which no web page is allowed to see — if yours has an iOS/Android switch, set it to Android. The quickest test is to open the timer, start a session and press the button: if the panel flashes, it works.

What happens when the clock runs out?

The same thing that happens in a real race. The session does not stop, it tells you to finish the lap you are on, and the next tap ends it. That way the lap count is comparable with a race of the same length. If the car does not make it back, End now closes the session without recording a final lap.

I double-tapped. Can I fix it?

Yes. Undo takes back the last lap while you are still timing, and its time folds into the next one. After the session the lap table lets you merge two laps into one, which is the fix for a double tap, delete a lap, add one the timer missed, or type a time in. Edited laps keep a small mark and the session records how many were touched. What the stopwatch originally saw is kept alongside, so a corrected session is never mistaken for an untouched one.

What analytics do I get from a saved session?

The same ones a scraped race gets, from the same code. A lap-time chart with a trend line showing whether you were building into the run or fading. Best lap, average lap, best three consecutive and a consistency score. A lap-by-lap table with the gap to your best lap and the predicted finish at that pace, which is what your lap count and total time would have been had you held it for the whole session.

What is the consistency score?

How tightly grouped your lap times are, from 0 to 100, where higher is better. It is the same figure and the same scale used on your driver profile and your race results, so a practice session and a race can be read side by side. A tidy touring run scores around 90, a scruffy one around 75. If it reads 0 the laps varied by more than half their own length, which usually means it was not really a session, for example pressing the button a few times to see what it does.

What is best three consecutive?

The quickest three laps you ran back to back, added together. It is the number most clubs use to rank a run because it rewards stringing laps together rather than one hot lap. It is the same quantity shown on race results, so the two compare directly.

How do I tell whether I am actually getting quicker?

Open Practice Sessions under Analytics and switch to Trend. It plots one point per session, oldest first, with best lap and average lap on the left axis in seconds and consistency on the right in percent. Filter by venue and class so you are comparing like with like. A few sessions in, the direction of travel is usually clearer than any single session was.

Can I compare two sessions directly?

Yes. In Practice Sessions, switch to Compare and pick any two. Both lap traces are drawn on one chart by lap number, so you can see where the time went rather than just that it went. Underneath is a table of the differences in best lap, average, best three consecutive, consistency and lap count, coloured for better or worse. If either session has hand-edited laps it says so, because the two are then not quite like for like.

Can I share a session?

Every saved session can generate a report card image: the headline numbers, the lap trace with your best lap marked, and the full lap list. Download it and post it wherever you like. There is also a short written read on the session, covering where the pace was, how steady it was and what to work on next time.

How accurate is tapping by hand?

Each tap carries roughly a tenth of a second of human reaction time. Against a nine-second lap that is about one percent, and it applies to every lap equally, so best lap, average and consistency are all worth comparing between your own sessions. Do not expect them to line up exactly with transponder timing, and treat differences smaller than a tenth as noise.

Is a lap recorded by sound or by remote any more accurate?

No, and it is worth being clear about it. You are still the one deciding when the car crossed the line, so the reaction time is the same whichever way you tell the phone about it. What they save you is having to find and hit a moving target on a screen, which is both the annoying part and, in practice, a little extra variation of its own. One thing to know about earphones: a Bluetooth microphone adds a fixed delay of a tenth or two before the phone hears you, which shifts when the session appears to start but cancels out of the lap times, because a lap time is the gap between two of them.

Does practice affect my race results?

No, and deliberately so. Practice sessions are stored separately and never reach personal bests, venue lap records, head-to-head, championships, badges or My Results. A hand-tapped lap should never become a track record. Practice has its own history, trends and comparison instead.

Can I import laps from another lap timer?

Yes, from LapMonitor. Export a session from the LapMonitor app as a CSV or JSON file. Then on Practice tap Import laps (top right), choose LapMonitor, and pick the file or drop it onto the box. You see each run in it with its date, laps, best lap, driver and transponder. Fill in the Garage and tap Import run. Imported runs are labelled LapMonitor on their card and work like any other practice run — trends, compare, the report card and notes. More timing apps will follow.

Where did the Lap Timer button go?

On Practice it is now Import laps, the one place every run comes in from. The first option in it, RaceMetrics RC Lap Timer, opens the Lap Timer as before. The Lap Timer is also in the menu.

What goes in the Garage when I import?

The same fields as the Lap Timer’s Garage, working the same way. Car starts on your primary car. Club only appears when the car is registered at more than one club, and sets the class. Where starts at the car’s club venue; tap it to see your recent places, search every track we know, or type somewhere we don’t and tap Use “…”. Your recent places are shared with the Lap Timer. Setup sheet starts on The sheet on the car that day, worked out for each run from its own date, because an imported run was usually driven a while ago. You can pick a particular version or No setup sheet instead. The import remembers what you chose last time, separately from the Lap Timer.

What date does an imported run get?

The date and time the session was driven, from the file — the Session Date in a CSV, the date in a JSON — never the day you imported it. It shows in the list heading and at the top of the run itself, marked (LapMonitor). If the date in a file cannot be read, nothing from that file is imported and you are told why, rather than the run being filed under today.

What happens if I import the same file twice?

Nothing is duplicated. A run is recognised by LapMonitor’s own session and driver ids, so importing it again — or importing the CSV after the JSON of the same session — just says it is already imported. The run you already have is left exactly as it was, so a different car or track picked the second time does not change it. To file it differently, delete the run (open it and tap Delete session) and import the file again.

Which laps come in from a LapMonitor file?

Every normal lap, with its time and when it was set. The first crossing that starts the clock is not a lap and is left out, as are laps LapMonitor did not mark as normal. If the file holds more than one driver or transponder with laps, each becomes its own run and you can untick the ones that are not yours. Imported laps are treated like practice: they never count towards race results or lap records.

Will my phone screen go to sleep mid-session?

The timer asks the browser to keep the screen awake while it is running, which most modern phones allow. If yours does not, set your screen timeout longer before you start. If the page is reloaded part way through, your laps are not lost. Reopen the timer and it offers to recover them.

map Find Tracks

Interactive map of every UK race track we know about.

What's the Find Tracks page?

An interactive map at /tracks showing every venue we have a geocoded location for. Pin clusters group nearby tracks when zoomed out; tap a pin to see a popup with the club's type/surface, classes raced, facilities, address, distance from your postcode (if you're logged in with one), and a link straight to the venue page.

Where does the venue info come from?

For venues matched to the BRCA club directory we pull rich metadata weekly — address, classes, facilities, opening hours. Other venues show whatever data we have from our regular race-data scrapes. The "Last synced from BRCA" line at the bottom of the Club Info modal tells you how fresh the BRCA-sourced data is.

What filters can I use?

Search by name, Within X miles of me (only when you're logged in with a postcode in your profile), Venue Type (indoor/outdoor), Track Surface, Scale (1/8th, 1/10th, 1/12th, Large scale, Micro / Mini-Z — auto-grouped from the classes each venue races), Facilities (camping, café, mains power, etc — "has all selected"), and a Live now toggle for venues with a meeting running right now.

What's the red pulsing pin?

"You are here" — your home location, geocoded from the postcode in your profile. Renders only when you're logged in and have a postcode set in Account → Preferences → Location. Distances on each venue popup are measured from that point.

Why isn't my local track on the map?

Most likely we don't have a geocoded location for it yet. If you know your venue's postcode, open the venue page → kebab menu → Submit Venue Info and add it. After an admin approves the submission, the venue will appear on the map automatically. Same flow works for adding the venue's BRCA club page URL, which then pulls in their full club metadata on the next sync.

tune Basic & Advanced Mode

The app comes in two sizes. Basic is the results and your garage; Advanced adds the deeper analysis on top.

What is Basic mode?

Basic is the everyday app: venues, meetings, race results, your own results, driver profiles, Head-to-Head, your cars and setup sheets, the lap timer and the gearing calculator. It is everything you need to follow a race weekend, with the heavier analysis tucked away.

What does Advanced add?

Everything in Basic, plus the analysis tools: the full Driver Performance panel (Lap Time Trends, Consistency, Venue Analysis and Race History), Compare Drivers, the Race Data Studio, Setup Sheet Analytics, the Race Playback Studio, Suspension Geometry, the practice trend and comparison charts, and the extra result columns (Lap Spread, Lap Trend and Predicted).

How do I switch?

Use the tune button at the top right, just to the right of the notifications bell. It never switches straight away: it opens a full list of what each mode shows so you can see exactly what changes before you commit.

Does switching to Basic delete anything?

No. Nothing is removed from your account and no data is touched. Basic only changes what is on screen and what is listed in the menu. Switch back and everything is where you left it.

Which mode am I in?

The button shows it: BASIC or ADV on a desktop, and a small dot when Advanced is on for phones. If you have never chosen, you are asked once when you sign in, and you stay on the full app until you answer.

I opened a link and it says the page is an Advanced feature

The page still works. Links you have been sent, saved as bookmarks, or tapped from a notification always open, even in Basic. The bar just explains why that page is not in your menu, and offers a one-tap switch if you want it listed.

Does my choice follow me to another device?

Yes, if you are signed in. The mode is saved to your account, so picking Basic on your phone gives you Basic on the laptop too. Signed out, it is remembered in that browser only.

cloud_sync Data Sources

Where the lap times, results, and venue info come from.

Which timing services do you support?

Three, covering most of the racing world:

• timer rc-results.com — the most widely-used timing service for UK BRCA-affiliated clubs. Our largest coverage area; most of the front-end was built around its data shape originally.
• hub rcresults.org — a self-hosted timing system run by individual clubs (some clubs label it “bbkRC”). UK-focused, smaller footprint than rc-results.com.
• public liverc.com — a global timing service used by clubs across the US, UK, EU, and beyond. Many LiveRC venues also publish live video broadcasts during racing.

Each venue is tied to exactly one of the three. The badge on the venue card on the home grid (filterable via the provider chips above the grid) tells you which one.

How often is each provider scraped?

Continuously, but at different cadences:

• Live state probes run every few minutes against each provider's index page so the “Live now” badge fires quickly when racing starts.
• Active meetings (currently racing) refresh every ~5 minutes so new heats and results land promptly.
• Concluded meetings get refreshed much less aggressively — once a meeting is finished its data is static, so re-scraping is a waste of upstream bandwidth.

New races usually appear within 5–15 minutes of being posted upstream.

Why isn't my club listed?

Either the club uses a timing system we don't support yet (e.g. MyLaps RaceMonitor, MyRCM), or we know about the venue but admin hasn't opted it in for scraping yet. Tell us the club's name and the timing site it uses and we'll take a look — adding a new provider is a project-sized job, but opting in an existing-provider venue is a few minutes.

Can I watch a live broadcast from inside the app?

Yes for LiveRC venues with a stream running — a red Watch live stream pill appears on the meeting page during racing and opens an embedded video player without leaving the app. rc-results.com and rcresults.org venues don't publish video.

Why do features vary between providers?

Each timing service exposes a slightly different data shape. Where rc-results.com publishes per-driver lap arrays in its race pages, rcresults.org puts them in separate lap-time pages, and LiveRC embeds them inside the race-result HTML. We unify all three into the same internal model, but some features (championships, finals overall rankings, qualifying summaries) only exist where the upstream provider exposes them — and a few brand-tinted UI cues (provider badge, source link in the venue footer) tell you which provider any given data point came from.

shield Privacy & Data

Where does the data come from?

Public race results, meetings, lap times, and driver names from the timing services listed under Data Sources (rc-results.com, rcresults.org, and liverc.com). We don't scrape anything that isn't already public on those sites.

Who can see my profile?

Anyone with the URL — driver profiles are public. Your Account, My Results, and saved setups are private to your login.

Can I hide my profile?

Not currently. Get in touch if this matters to you.

How long is data kept?

Indefinitely. We don't auto-purge — historic data is part of what makes the app useful.
