How to Erase an App From the iPad
You can erase apps directly from your iPad without the use of iTunes. While you cannot delete the built-in apps that came pre-installed on the iPad, you can remove third-party applications whenever you want. Third-party applications include any app you purchased and downloaded from the Apple App Store. Erase these apps from your iPad to unclutter your Home screen and to free up space on the device.
Touch and hold an app icon on your Home screen until all the app icons begin to wiggle.
Tap the small "X" symbol in the corner of the app icon you want to erase. A confirmation message appears on your screen.
Tap the "Delete" button of the confirmation message to erase the app from your iPad.
