How can we help?
Most questions are answered below. For anything else, a direct contact will live here soon.
— Common questions
- Why is my heart rate not showing during a ride?
- MTB HUD reads heart rate from a paired Apple Watch via HealthKit. Start a workout on your Watch (any workout type works) before or during the ride. If you forgot, the app shows a gentle reminder.
- Where is my ride data stored?
- On your phone. MTB HUD uses SwiftData locally — nothing is uploaded. You can export your full history as JSON from the ride summary.
- Why don't I see the AI ride narrative?
- The AI title and narrative use Apple's Foundation Models framework, which currently runs only on iPhone 15 Pro and newer with iOS 18 or later. On other devices, the rest of the summary works as expected.
- Does MTB HUD drain my battery?
- GPS during a ride is the main draw. A typical 2-hour ride uses about 20–25% of an iPhone's battery with the screen on. When you pause a ride, sensors stop and the drain is minimal.
- How do I delete a ride?
- Open a ride summary, tap the share menu (top-right), then choose Delete Ride. Or swipe a row in the history list.
- Can I use MTB HUD without an Apple Watch?
- Yes. Everything except live heart rate works phone-only. A Watch is recommended but not required.
