We knew something like this was in the works for Lumia Black, but Nokia decided to throw it out on the market without the need of Lumia Black. App Folder lets you simple start and group, name it, then pick the apps you want to go in it, and pin it to your start screen.
The regular live tiles look better than the folder version you put them in, but it is a nice way to clean up your home screen. All the app you put in a folder basically turns that folder into a live tile for the apps you selected to go in that folder.
App Folder is definitely a great start, and as many apps as some of us have it is a great feature to use. Click HERE to download App Folder and clean up that start screen.
