How Do I Delete An App On My iPhone?
Hold your thumb down on the app you would like to remove from your iPhone. After a couple seconds, all of the app icons will start to shake. A black and white X will appear at the top left corner of your third-party app purchases. Click on the X to remove the app. Note: the default apps like Maps, Weather, Clock, Safari, etc. cannot be deleted.
This method works on all iOS devices.
