How to delete an app

1. Touch and hold the app.

2. Tap Remove App.

3. Tap Delete App, then tap Delete to confirm.

Keep in mind that some built-in Apple apps can't be deleted from your device, so you might not see the option to delete an app. See this support article for a list of built-in Apple apps you can delete from your device: Delete built-in Apple apps from your iPhone, iPad, or Apple Watch - Apple Support If you can't delete an app that's not made by Apple, disable parental controls as outlined in this article: Use parental controls on your child's iPhone, iPad, and iPod touch - Apple Support then try deleting the app again.

If you touch and hold an app from the Home Screen and the apps start to jiggle: 

1. Tap the Remove icon in the upper-left corner of the app.

2. Tap Delete App, then tap Delete to confirm.

3. Tap Done.
