Restarting the Apple Watch App.
Normally you will not have to restart the Apple Watch app. This usually indicates communications issues between the Watch and the iPhone it is paired with.
To achieve a restart of eKeypad on the Watch you will actually need to restart all apps. There is no way to stop a single application.
- Press and hold the side button. This is not the Digital Crown, but the oblong button beside it.
- After a few seconds the Apple Watch will show a shut down screen.
- Release the side button, then press and hold it once more for several seconds.
- The Apple Watch will automatically return to eKeypad, close it automatically, and open the home screen.
