It is sometimes annoying with the number of apps that crowd your iPhone’s home screen. You probably welcomed a feature that originally came with iOS 14: the App Library, which gathers all of your apps into various categories and displays them on a separate page to the right of your home pages.
The App Library not only adds some automatic organization to your iPhone’s home pages but also allows you to clean up your home screen by hiding as many apps as you want.
You can organize your current apps by hiding some of them, there are several ways to do it. You can remove individual apps from the home screen, you can hide an entire screen of apps, or can organize several apps by putting them into a folder.
