1. Download and install the app, then grant Location and Motion permissions for accurate GPS timing. 2. Create a driver and vehicle profile, choose a track from the built in database or let the app auto detect when you arrive. 3. Mount your phone securely with clear sky view, select Start session, and enter the track when directed by event rules. 4. Drive your laps while the app auto detects start and finish lines, shows live lap and split times, and records speed and position. 5.
