How to: Close an App that is running
The iPad doesn’t need you to close a running app for every instance. But in some cases like playing a game, you may need to actually close the app in order to start a new level rather than continuing the last.
Here are the steps to follow:
1. Click your iPad’s Home button to minimize the app if it’s running.
2. Double-click the Home button or swipe up with 4-5 fingers to see a row of running apps.
3. Swipe up the thumbnail of the running app to close it.
4. Click the Home button again to return to the Home screen.
