FastTrack

Time your runs to the millisecond. FastTrack turns your iPhone into a GPS-accurate 0-60, quarter-mile, and roll race timer - with a garage, feed, and leaderboards.

FastTrack is a precision vehicle performance timer and enthusiast community built for track days and closed-course testing. Measure acceleration, rolling speed, and drive sessions with GPS accuracy - then share results, buy and sell parts, join groups, and drive with friends in real time.

0-60, 0-100, quarter-mile, and half-mile times with millisecond precision. Automatic accelerometer-based launch detection. Sensor fusion of GPS and high-frequency accelerometer matches dedicated timing hardware within #0.02 seconds. Strict rest-anchored times or 1-foot rollout (Dragy-style) display. Per-milestone validity keeps a clean 0-60 even if a later split looked off. Downhill runs are detected and excluded from public boards.

ROLLING MODE

Time rolling-start pulls. Hit 60 mph and the timer starts automatically - capturing 60-130, 60-100, and 100-150 mph with 10 mph splits and peak G-force.

DRIVE TRACKING

Real-time speed, distance, max/average speeds, and an interactive route map. Background GPS keeps recording when your screen is off.

DRIVE WITH FRIENDS

Multiplayer sessions joined with a 6-character code. Cruise, race, rolling, or open modes. Friends on a shared live map, real-time stat compare, podium summaries.
