Here is something interesting that I just discovered. When on the Home screen on Apple Watch, drag your finger around the screen to find the app you wish to open. Make sure that app is centered, and then rotate the Digital Crown upward. This will open the app.
You can also zoom out all the way and see every app you have on one screen. Of course, it is nearly impossible to see them all because they are so tiny, but it helps you navigate to a location better.
If you zoom using the Digital Crown while the Watch app is highlighted, you will zoom into your watch face. It’s pretty cool.
