It can be a little hard to find the app you want to use on your Apple Watch. That grid view is small and dense, and the list view, while better, means a lot of scrolling on a very tiny screen.
Fortunately, watchOS 6 will improve app organization by making it possible, for the first time, to delete some of the stock apps installed on every Apple Watch. Not only will this reduce clutter in the app picker, but it can free up a little bit of storage space, which can be at a premium if you store music, podcasts, or audiobooks on your Apple Watch.
