delete apps

When you hide an app on your iPhone, iPad, or iPod touch and you view it in the App Store, it won't look like you bought it. That means hiding will not remove from Home Screen it will still appear on your home screen.

But hiding the app won't delete it from your device or other devices that are signed in with the same Apple ID. Learn how to delete apps downloaded to an iPhone, iPad, or iPod touch. To completely remove an app from your home screen, you need to delete it.

As far as hidden apps are concerned, you need to unhide them, using the latest version of iTunes on a computer.
