In Grid View on your Apple Watch, apps are shown as icons in a kind of honeycomb formation that moves with your finger. Since the introduction of watchOS 4, you can switch from Grid View to List View. This will present your apps as an alphabetized list. I prefer List View as it's easier for me to find apps by title rather than by their icon on the Apple Watch, and the touch target in List View is larger so I don't accidently open the wrong app as much. Also, List View is just easier for me to look at, as the shrinking-enlarging movements of apps in Grid View can give me a headache.
