Bluetooth-synced race starts with sensor-fusion 0–100 and drag timing.
Synchro Race Timer is a performance timing app for closed tracks, drag strips, and private roads — built for drivers who want synchronized multi-phone starts and precise acceleration runs.
Timing and sync
- Solo mode: local countdown and timing when you are alone — no Bluetooth required
- Multi-driver sync: one host creates a Bluetooth LE session, friends join
- Shared countdown and simultaneous GO! signal across devices
- High-rate accelerometer launch detection (overcomes ~1 Hz GPS lag)
- GPS + IMU blending for smoother speed and distance curves
- Slope / gradient fairness checks to flag downhill advantage
- Units for Europe and the USA: km/h or mph, meters / feet / miles
Free includes a 1v1 Bluetooth LE lobby, the last 5 runs, and ads on History and Settings. Synchro Pro unlocks a lobby for up to 8 devices, unlimited history, charts and CSV export, and removes ads.
Use only on closed courses and private roads. Obey all traffic laws. Maxsoft Software is not liable for misuse, accidents, or vehicle damage.
