If you're like most iOS users, you have lots of apps. It's all too tempting and all too easy to buy new ones (or download free ones) from the App Store. As a result, you probably have a number of games, productivity apps, and utilities on your iPhone or iPad that you've hardly ever used and aren't likely to use in the future.
But if you keep doing that, those apps will start to crowd your iOS device (and your iTunes library), taking up space and requiring frequent updates. That's why it's a good idea to periodically get rid of the apps you don't use anymore. (You can always download them again from the App Store if you change your mind.) Culling your apps library can make managing your app collection easier and free up precious storage space. Here are four ways to do it.
Tap and wiggle
Deleting apps on an iOS device is simple: Just tap and hold any app icon until all the icons start wiggling. You'll notice that many, if not most of them, have a little X at the top left corner. (The ones that don't have the X are default apps that are part of iOS; you can't delete those.)
To delete an app, tap the X, then tap Delete in the dialog the displays. Note that doing so deletes not only the app, but also all of its data. So if you think you'll need an app again soon, and you have stored data, settings or completed levels and it, you might want to think twice before tapping on that X.
Another way to delete apps on an iOS device is from the Settings app. Tap Settings > General > Usage, then look at the apps that display at the top of the window in the Storage section. This list is useful, because it shows how much storage each app actually uses. That may include just the app itself or the app plus all its attendant files and data. If you need to free up a specific amount of space--perhaps when you want to download a movie--this is a good place to look.
Deleting from here is simple, too: Tap on an app's name, then tap Delete App. You may find this quicker than tapping icons if you want to delete a lot of apps at one time.
When you delete apps from your iOS device, iTunes will not copy them back on to your device the next time you sync it. So the above techniques are great if you want to delete apps from specific devices but still retain them in your iTunes library.
