Wake the Watch to Your Last App
Lift or jostle your Apple Watch, and the screen will wake to show you the time and any notifications. But if you are using a specific app intermittently to check on a status or manage messages, etc., this can get a little annoying since you have to unlock the screen every time.
Fortunately, there’s a way to change this. Go to Settings, then General, then Wake Screen. Here you’ll find options to automatically wake your Watch up to the last app that you were using. You can set it only to do this if you used the app in the last couple of minutes or increase the delay to up to an hour.
