How to Delete Apps on an iPad
Tap and hold an app until all the apps on the screen begin to jiggle.
Tap ⓧ in the upper-left corner of the app you want to delete.
Some default Apple apps, like App Store, Settings, Contacts, and Safari, can’t be removed and will not display an ⓧ.
Tap Delete to confirm deletion of the app.
Tap Cancel if you change your mind or made a mistake.
