How to close a running app on your IOS device including iPad, iPhone or iPod touch
Since Apple introduced multitasking on IOS devices you’ve been able to run different apps on your device and leave them running in the background while you use another app.
This is great, but sometimes you want to close the app – sometimes it’s because your iPad is running short on memory or maybe an app has stopped responding. Closing and relaunching the app quite often fixes this.
1. To close an app double-tap on your home button (below)
2. The bottom bar now shows a list of all the apps on your iPad which you are currently running:
3. Tap and hold one of these icons until they wiggle and red minus signs appear next to each icon.
4. To close an app just tap on the minus sign next to it. This won’t delete your app, it will just close it.
To exit this mode just press the ‘home’ button again.

To close an app just swipe it upwards.
