Your phone is the timing gate. FPV Lap Timer uses your phone's camera to count laps automatically - no transponders, no timing gates, no extra hardware. Mount your phone at the start/finish, line the gate up with the on-screen center line, hit Start, and every time your quad crosses the line a lap is recorded. That's it. Built for FPV, tinywhoops, and drone racing practice, whether you're grinding a backyard gate or dialing in a full track.
