Open the app switcher and swipe the app's preview upward.
Step by Step
- On a Face ID device, swipe up from the bottom and pause to open the app switcher.
- Find the app.
- Swipe its preview upward to close it.
- Reopen the app.
If That Doesn't Work
- Normally you do not need to routinely close every app; iOS manages suspended apps.
- Force-closing is most useful when an app is not responding correctly.
