Apexlog turns your iPhone into a telemetry logger for your motorcycle, car, or any vehicle. Mount it, hit record, and capture your GPS track plus high-rate motion data (accelerometer + gyroscope). Review every ride later on a map, with a G-G friction circle and vehicle attitude — lean, pitch and heading — derived by fusing the sensors.

REPLAY & ANALYZE
