Live telemetry
Your lap times, live everywhere
Track your laps. Share with your crew. Improve every session.
The paddock app for track day drivers. Record laps from your phone, stream live telemetry to the paddock, and build your session history. Stay connected with your crew and the wider track day community between sessions. You do not need extra hardware to get started.
Track
Phone GPS: open the free app, pick your track, and drive. The catalog syncs to your phone, and automatic finish-line detection gets you timing without buying hardware. Pair a RaceBox over Bluetooth for 25 Hz GPS and more accurate lap timing.
Share
A low-latency live telemetry stream sends lap times, GPS, and session data to the paddock feed and the cloud while you drive. Join crews, follow the activity feed between track days, put a QR code on your car for Driver Bio, and send replays before you hit the pits.
Improve
On the Drive screen, chase the Time to Beat while other drivers' laps land in real time. After the session, review head-to-head replay on the map and coach debrief notes.

Lap timing from your phone

Drive screen: your laps, rivals, and time to beat
The in-car Drive screen is your timing HUD — live lap clock, session best, previous lap, and a Time to Beat card for whoever holds the fastest lap on track. Your Laps and Other Drivers lists update in real time as sessions run at the circuit.
