Tap and Wiggle
If you’d like to get rid of an application on your iPhone that you don’t use anymore or need to free up some space, you can tap and hold any app. All the apps will start wiggling and an “x” should appear in the upper left corner of the app. Tap on the “x” and tap “Delete” when prompted to erase application.
Remove through Settings
You can also remove apps through your settings by selecting the “Settings” app, tapping “General”, tapping “iPhone Storage”. An accumulated list of all your applications will appear and you’ll see apps currently installed and how much storage space each app is taking up. All that’s needed to do here is tap on the app and then tap “Delete App”.
