Once upon a time, iOS could run only one app at a time, and the only way to “switch” between apps was to press the Home button to exit the current app and then open another. In recent years, the App Switcher has let you quickly flip between open apps, peek at their contents, and close them. In iOS 8, the App Switcher now also provides shortcuts to your recent contacts and to Handoff ①.
① The App Switcher is a beautiful way to flick between open apps.
If the app you are switching to is coming from Handoff (see About Handoff), flick right. The Handoff activity screen is always at the left of the App Switcher.
Certain location-based apps appear in the App Switcher automatically, to the left of the Home screen. Tap the app to open it. For example, if you have the Apple Store app installed and are near an Apple Store, that app appears.
You can turn this feature off entirely in Settings > General > Handoff & Suggested Apps.
