If you’re like most people, you probably use iTunes to manage your music, movies, and books. But there are also a number of apps that you can add to your account. To delete an app from your account, open the App Store on your device and select the app you want to delete. Then tap on the three lines in the top left corner of the screen and select “Delete.”
Open iTunes and select the app you want to delete.Press the “X” button in the upper-right hand corner of the app. The app will be deleted from your iTunes account, but it will still exist on your computer until you delete it manually.
You can delete apps from your iPhone, but not from iTunes. To delete an app from your iPhone, go to Settings > General > Usage > Storage and tap on the app you want to delete. Tap Delete App and confirm deletion.
