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.
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.
- Race replay: your line and speed, lap against lap.
The app is free. Get boxbox, or read the karting guides.
