To stop the wiggling, press the home button on devices that have it or tap Done on the top right for those that do not. Apps will start to wiggle and a small minus symbol appears on each icon. To delete apps from the home screen, place your finger on an app you want to delete and hold. Any purchased app is always available to re-download again at no extra charge from the App Store. On that device storage page, look for apps you don't use.Tap them and select Delete App.
