BoxBox: Motorsport Lap Timer

BoxBox turns your iPhone and Apple Watch into a lap timer, telemetry system and live pit wall for karting, formula and GT racing.

Drop your phone in the car, strap on your watch, or pair a RaceBox over Bluetooth for 25 Hz GPS: BoxBox times every lap automatically, shows your live delta, and speaks your gaps so your eyes stay on the track.

TIME: automatic lap detection on any circuit, live delta to your best, sector timing. Tracks are created on the go, no library to download.

REVIEW: every session saved with full telemetry. Replay your line on the map coloured by speed, braking in red, lap against lap, and find the corners where the time is hiding.

SHARE: go live so friends, coach or team can watch your session in real time, lap by lap, with your position on the track map.

APPLE WATCH: start a session from your wrist, with or without the phone in the car. Last lap, best, live delta and your heart rate on the watch. One tap for a good lap, two for a slow one. Start on the phone and the watch mirrors it, or the other way round.

APPLE HEALTH: turn it on and your heart rate and active energy from Apple Health are kept with every session, so you can see how hard each stint really was.

BOXBOX PRO: optional monthly subscription that unlocks your complete session history and everything we ship next. Payment is charged to your Apple Account; the subscription auto-renews monthly unless cancelled at least 24 hours before the end of the period. Manage or cancel in Settings › Apple Account › Subscriptions.
