Delete Any Apps You Don’t Use
First things first, delete all of the apps you don’t use. All of those unused applications aren’t doing anything except cluttering your app grid, which makes useful apps more difficult to find.
You can jump into Settings > General > iPhone Storage to see the apps you don’t use regularly (or at all).
From here, you have a couple of options. You can use Offload Unused Apps, or you can simply delete them.
The second method is recommended. It also helps to apply wardrobe-like cleaning ideas to this. If you’d like to keep an app, see if you use it within the next month. If not, delete it.
