Every car timed. No transponders.
Each driver’s phone times their laps with GPS, so the organizer gets live times for the whole field without renting transponders, laying a loop or staffing a timing tower.
Organizers who want lap times for every car without renting transponders or laying a timing loop.
Simulated demoYour channel shows Fastest laps. Lapping days rank by best lap: no race positions, no race language.
01The problem today
The problem today
- 01
Transponders cost and go missing
Renting, handing out, charging and collecting transponders is a job in itself, and lost units come out of the event budget.
- 02
Not every track has a loop
Many venues, skid pads and airfield events have no installed timing loop, so drivers get no times at all.
- 03
Times stay in the timing shack
Drivers want their laps, sectors and progress on their phone, not a printout at the end of the day.
02What TRACK gives you
Built for how you run the day.
GPS lap and sector timing in every car
Directional timing-line crossing with interpolation between GPS samples. Every lap carries its own uncertainty, and invalid laps (pit, off, low confidence) are flagged instead of counted.
Built · tested in simulation; field validation pendingMore →Accuracy you can see
In TRACK’s tests on simulated laps, phone GPS timing had a median error of 0.037 s; with a 25 Hz receiver it fell to 0.007 s. Each time shows its uncertainty, so close calls aren’t over-claimed.
Simulation results · reference-logger test pendingMore →Live fastest-laps board
Times from every consenting car feed one board for the venue screen and a share link, ranked by best lap on lapping days, or by class for time attack.
Simulated demoMore →Upgrade the precision per car
Drivers who want tighter times add a 25 Hz GPS receiver; the timing engine uses whichever source is best.
RaceBox: awaiting hardware validationMore →Times in every driver’s pocket
Laps, sectors, ideal lap and session reports land in each driver’s app straight away, and stay theirs to keep and export.
In the app betaConsent first
Drivers choose whether their position and times are shared with the event. Private drivers are still timed for themselves, never shown.

03Example
Lakeside Autoclub · Spring Open Lapping
Illustrative scenarioIllustrative scenario: 48 cars in four run groups at a circuit with no rented timing system.
The club used to hand out rented transponders at registration and chase them down at the end of the day. This time, drivers scan the invite QR at the drivers’ meeting and mount their phones as usual.
From the first session, a fastest-laps board runs on the paddock TV and on a link families open on their phones. Each driver sees their laps, sectors and ideal lap in the app between sessions.
At the end of the day the organizer exports the results by run group. Nobody counts transponders back into a box.
- ✓No transponder rental or collection (illustrative)
- ✓Every consenting car on one live board
- ✓Drivers leave with their own lap data
- ✓Times labelled with their uncertainty

Drivers’ meeting
Drivers scan the invite QR and choose what they share. The Entrants tab fills as they do.
- 08:30
Confirm the timing line
The organizer confirms the venue’s start/finish line once in the Atlas. Unconfirmed lines never arm timing.
- 09:00
Novice group out
Phones time every lap from the first flying lap. Invalid laps are flagged, not counted.
- 09:30
Board on the paddock TV
Fastest laps by run group, ranked by best lap, with no race positions on a lapping day.
- 16:30
Results out
Export results per group. Drivers already have their sessions in the app.

Questions organizers ask
Is GPS timing as accurate as transponders?
Not yet for official results. Loop-based transponder systems are the standard for sanctioned racing. TRACK’s GPS timing is designed for lapping days, schools and club events, shows each lap’s uncertainty, and has been validated in simulation; a test against a reference logger is next.
What if a driver doesn’t run TRACK?
Only cars running the app are timed. Mixed events can keep their existing system and use TRACK for the drivers who opt in.
Does it work without mobile coverage?
Timing runs on each phone and works offline. The live board needs a connection at the venue to update.
Can it time autocross or cone courses?
Circuit lap timing with a start/finish line is what’s built today. Separate start and finish for point-to-point runs is on the roadmap.
