Remove apps from iPod touch
You can easily remove apps from your iPod touch. If you change your mind, you can download the apps again later.
Remove apps from the Home screen
Touch and hold any app on the screen until the app icons jiggle.
Tap on the app you want to remove, then tap Delete.
Press the Home button.
If you change your mind, you can redownload apps you’ve removed.
In addition to removing third-party apps, you can remove the following built-in Apple apps that came with your iPod touch:
Contacts (Contact information remains available through Messages, Mail, FaceTime, and other apps. To remove a contact, you must restore Contacts.)
Note: When you remove a built-in app from your Home screen, you also remove any related user data and configuration files. Removing built-in apps from your Home screen can affect other system functionality. See the Apple Support article Remove built-in Apple apps from the Home screen.
