Watch App Crashes

If you can not start the app

Please try reinstalling the Watch app and restarting Apple Watch / iPhone.

The app crashes during measurement

The Apple Watch itself may be unstable, so please try restarting it.

We have seen many cases of crashes where the Zones app was not a factor.
If it's a problem with your Apple Watch or Apple Health, or a problem with watchOS, restarting your Apple Watch will often fix the problem.
Alternatively, it may be fixed by re-pairing the Apple Watch.

If you find a way to reproduce the crashes, it would be greatly appreciated if you could feedback us via Settings > Support > Feedback.

Recovery after a crash

If the Watch app crashes, the app will automatically recover and resume, or resume when the app is launched again.
