Most iPhone users switch between apps by returning to the home screen and selecting the app they want to use next. But if it’s an app you’ve recently used, did you know there are two faster ways to get back to it?
If you’re on an iPhone with a TouchID sensor, double click it. If you’re on an iPhone with a FaceID sensor swipe up from the very bottom and stop halfway up.
You’ll be presented with a row of apps in card form ordered by how recently you used them. You can then swipe left and right and select an app. If you’re on an iPhone with a FaceID sensor you can also swipe right to go a previously used app and jump back quickly by swiping right.
After a few seconds the app will re-order itself to be the rightmost app. You can then swipe left again to go back.
