boxbox
boxbox turns your phone into a full pit wall for karting, formula and GT racing: live lap timing with predictive delta, an audio engineer calling laps and gaps into your helmet, and a live pit wall your coach, family or team can watch from anywhere: timing, map and radio. Add friends and family and they see your races live, from the pit lane or from home, and you see theirs. It runs on Apple Watch too: start a session from your wrist, with or without the phone in the car.
Start a session and drive. Afterwards, replay every lap, see where the time lives, and keep a history for every track.
- Predictive lap delta: live gap to your best lap, corner by corner.
- Audio race engineer: lap times, deltas and gaps, eyes on the apex.
- Live pit wall: your crew follows the session in real time.
- Friends and family: add them with a code or a QR scan, and watch their race live while they drive, from the pit lane or from home. They watch yours the same way.
- Live alerts: a notification the moment a friend goes on track, and one when someone adds you.
- Race replay: your line and speed, lap against lap.
- Compare: the ghost of your best ever lap at the track, live and in replay. Its line under yours on the map, its speed trace under yours on the graph, the gap at every metre and sector by sector, plus the optimal lap your best sectors add up to.
- Apple Watch: a lap timer on your wrist, on its own or mirrored from the phone. One tap for a good lap, two for a slow one, and your heart rate saved with the session.
