Apps on your iPhone or iPad may occasionally crash or behave erratically. When this happens, you can close the app with the built-in app switcher function. Restarting the app is your best bet for fixing most problems.
Start the app switcher first
To close an app on an iPhone or iPad, you need the built-in App Switcher. This feature is essential for multitasking. It allows you to manage which apps are running and switch between them easily.
Here's how to start the app switcher:
- on iPhone X or later / iPads running iOS 1
- On iPhones and iPads with Home buttons: Quickly double-click the Home button.
With the app switcher we force an app to close. This means that the app must be restarted and reloaded when you tap on it. This method can fix some temporary problems you may have with an app.
Closing an app using the app switcher on the iPhone
Once the app switcher is started on your iPhone, you will see a screen similar to the one shown below. Large thumbnails of all the apps you've recently opened are visible on the screen; you can swipe left or right to see through it.
Swipe through the thumbnails until you find the app you want to close and center it on the screen.
Quickly swipe up on the app thumbnail until it disappears from the screen.
After that, the thumbnail no longer appears on the app switcher's screen because it is now closed.
To restart an app, find the icon on your home screen and tap it.
Closing an app with an app switcher on iPad
After launching the app switcher on your iPad (as described above), you will see a grid of thumbnails of all the apps you have recently opened. If you've been using a lot of apps lately, you can swipe left or right until you find the app you want to close.
Quickly swipe up on an app thumbnail until it disappears. If you want, you can use more than one finger to close more than one app at a time.
After you wipe out an app thumbnail, it is closed and will no longer appear on the app switcher screen.
To restart an app, tap the icon on the Home screen. This should restart the app and (hopefully) it will work fine this time.
Still having problems with an app?
If, after all this, an app still crashes, freezes, or otherwise gives you problems, try restarting your iPhone or iPad. If that doesn't help, there are some other techniques you can try including updating or reinstalling an app. You can also try to contact the developer of the app and explain the problem. Good luck!
