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.
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.
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.
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.
In the app
Open the app, select Phone GPS, and drive. The track catalog syncs to your device. Curated finish lines time laps immediately, and other tracks learn the line when you return to start.
Explore all features
While you are on track, the Drive screen shows who is running, who holds the fastest lap, and how your session stacks up. No radio. No pit board.
The Drive screen is your in-car timing HUD — live lap clock, session best, previous lap, and a Time to Beat card updated as other drivers cross the line.
Chase the leader from the seat, not just from the paddock.
Stick a QR code on your hood. Anyone in the paddock can scan it and see your fastest laps, seat time, and track history right away.
Your Driver Bio is a living racing resume. You do not need spreadsheets or screenshots. Your link stays current every time you hit the track.
