APPLE WATCH
Start and stop regular ride recordings directly from your wrist while your iPhone stays securely mounted. View speed, distance, duration, top speed and completed sprint results.
Optional Race Training records your heart rate, keeps the live Watch display active and saves the workout to Apple Health when Health access is granted.

EXTERNAL GPS
Track4Facts PRO supports:
• Dual XGPS150 and XGPS150A
• Dual XGPS160 SkyPro
• Dragy Lite with selectable update rates of up to 25 Hz
Higher GPS update rates provide more position and speed samples per second for more detailed sprint, distance, lap and sector measurements.

RESULTS YOU CAN TRUST
Track4Facts evaluates the GPS quality behind every measurement. It detects confirmed standstill, interpolates measurement thresholds and checks for GPS gaps, poor accuracy and implausible speed changes.
Unreliable attempts are marked accordingly instead of quietly displaying a result. Every drive retains its original measurement configuration, so changing your settings never rewrites previous results.
The measurement methods and their limitations are documented inside the app. Track4Facts PRO is not a calibrated measurement instrument.

SAFETY NOTICE
Performance, sprint, distance, lap and sector measurements must only be carried out on private, closed-off or expressly approved tracks and areas.
Secure your phone safely before driving and never operate the app while driving. Use is at your own risk. Always comply with applicable laws and safety requirements.
