Time your laps at Marysville Raceway

Lapforge knows Marysville Raceway: when you arrive, it recognizes the track from your phone's GPS and draws this outline on the timing screen with your position on it.

Press GO, tap Set start line as you cross the line on your first lap, and Lapforge saves that line for every visit. Each lap after is timed from GPS, placed between two GPS readings rather than rounded to the next one. Lap timing and your lap history are free, with no account.
