Lap timing that tells you the truth.
Record a session, import one from whatever box you already own, or put a live timing screen on the clubhouse wall. Free for racers, permanently.
Record on track
A RaceBox over Bluetooth, or any logger you already own — SpeedAngle, RaceChrono, down to a hand-made CSV with a position and a timestamp.
Lap times you can trust
The same lap engine runs on your phone and our servers, so the two cannot disagree — checked against a commercial timer to within 8 ms.
Share on your terms
Private, friends, or public — chosen per outing. The venue gets your times; the trace of where you went stays yours.
Find the circuit you drive.
Every venue on Apex, with the tracks it runs, the configurations you can actually drive, and the ranked and practice boards for each. No account needed to look.
Every lap you have ever driven, in one place.
- Replay any outing — the lap on the circuit, coloured by speed, with the delta ribbon showing where the time went.
- Import your history — files from the device you already own count. A hand-made CSV counts.
- Your number, your colours — how you appear in every tower and on every map.

A pit wall for the clubhouse, and a device pool that runs itself.
- Live timing on any screen — tower, speed-coloured map and delta ribbon, readable at ten metres.
- Run the day — sessions and groups on a running sheet that copes with rain, reordering and a skipped group.
- Lend devices, keep the times — issue a pooled RaceBox to a walk-up rider; the data follows whoever holds it.

Not every source measures the same lap the same way.
A phone at 5 Hz carries about 175 ms of timing error — wider than the gap between first and third at most club events. Ranking it against a 25 Hz logger would produce a board whose order partly depends on which phone you own. We keep two boards instead, and say which one your laps are on and why.
| Source | Rate | Typical error | Board |
|---|---|---|---|
| RTK logger | 100 Hz | 0.5 ms | Ranked |
| RaceBox | 25 Hz | 28 ms | Ranked |
| Good phone GNSS | 10 Hz | 49 ms | Practice |
| Typical phone GNSS | 5 Hz | 175 ms | Practice |
Measured against synthetic circuits with analytically exact lap times, and checked against real sessions from a commercial lap timer — where our lap times agreed with the device to within 8 ms across its own timing lines.
Video overlays
RaceChrono already does that well and we will not match it. Apex is timing and data.
Public-road sessions
Recording only starts inside a recognised circuit. If we do not have yours, ask and we will add it.
Charging racers
Venues pay a small fee to lend out a pool of devices. Everything else is free.
