The grid view of app icons on Apple Watch acts like the macOS dock, making apps that are closer to the center larger. Swiping around a large collection of apps floating like bubbles is not everyone's favorite interface. For those who prefer to see app names, a scrollable list may be easier to use. Switching between the two is accomplished with a few taps.
The app view can be changed at any time, either on the paired iPhone or on the Apple Watch directly. Once the app view is switched to a list, the Digital Crown can be used to browse apps.
