Ratings & Reviews
- This app has not received enough ratings or reviews to display an overview.
- Standing-start launch tests now begin at first movement, not at 5 km/h. Your 0–100 time is your real 0–100 time.
- Braking tests wait for a confirmed deceleration event, so coasting or lifting off the throttle no longer triggers a false start.
- GPS fixes are no longer rejected because velocity is still being computed — the most common cause of "GPS lost" reports on older iPhones.
- Routes, CSV and GPX exports no longer contain stuck points or straight-line jumps from tunnels and underground parks.
- Zero out the phone-mount offset for accurate motorcycle lean angles.
- Send Feedback directly from Settings → About.
- Live GPS Diagnostic shows fix quality, accuracy and permissions at a glance.
- Imperial units now apply everywhere — Home Screen widget, Live Activity and saved runs.
- Long, high-rate sessions no longer freeze Logs, Stats or session detail when opening them.
- Performance test attempts no longer create extra entries in your ride history.
- Now available in French, Italian and Dutch.
