Over time, you may need to do some housekeeping on your iPad to free up some space, especially if you download a lot of apps. Chances are you have some that you don't currently use and some that you just don't want to keep but haven't got around to deleting. You can remove apps from your iPad by putting your device into an editing mode known as the jiggle. Or, if your iPad is connected to iTunes, you can remove apps from your computer.
Remove Apps from an IPad
Tap and hold down the app you want to remove until all apps start to jiggle from side to side. An X also appears in the corner of some apps.

Tap the X on the app you're removing. If you don't see an X, you're dealing with a stock iOS app, such as Newsstand, Notes and Game Center. Apple preinstalls these apps and does not allow you to remove them.
Select Delete in the confirmation window to remove the app. When it's gone, press the Home button to exit editing mode and return to the normal screen.
Remove Apps in ITunes
Connect your iPad to your computer and select its icon from the iTunes menu to open the information page. Select Apps in the Settings area.
Scroll though the Apps list to find the one you want to remove. If you have a lot of apps on your iPad, you'll get to it more quickly if you type its name in the search bar. Select the Remove button -- its text will change to Will Remove.
Select Apply at the bottom of the page to begin the removal process. Select Remove in the confirmation box and wait for your iPad to finish syncing. When it's done, the app disappears from your iPad.
To reinstall an app from your iPad, tap the "App Store" and then "Purchased". Go to "Not on This iPad", find the app and tap the download button. To reinstall from iTunes, follow the steps to remove an app but select "Install" rather than "Remove".
You can delete apps permanently from your iTunes library if you know you won't ever reinstall them. Go to "Apps" in iTunes, find the app in the list and right-click it. Select "Delete" from the menu and then "Delete App" on the confirmation message.
You can also use "jiggle" mode to reorder apps on a screen or move them to different screens. To move to a new screen, drag the app to the side of your iPad until it moves across.
If you don't use some preinstalled Apple apps and find them irritating, move them across your iPad in "jiggle" mode until you create a new end screen where they'll be out of your way. You can also create a folder to store system apps.
Removing an app from your iPad also removes its data. This won't come back if you reinstall the app.
