Force closing an app on iPhone means swiping it away from the app switcher, not restarting your phone
When an iPhone app freezes, stops responding, or gets stuck on a loading screen, force closing it will shut it down completely. This is different from simply closing the app normally — it stops the app even if it's not responding to taps. The app will start fresh the next time you open it.
Force closing works because it cuts off the app's access to your phone's processing power and memory. The app doesn't get a chance to save its state or finish whatever it was doing — it just stops. This is safe to do and won't damage your phone or the app itself.
Key Takeaways
- Swipe up from the bottom of the screen (or swipe down from the top right on newer iPhones) to open the app switcher, then swipe up on the frozen app's card to close it.
- Force closing an app is safe and won't harm your phone or delete your data — the app simply stops running and restarts fresh when you open it again.
- If an app keeps freezing, force close it, wait a few seconds, and reopen it; if the problem continues, restart your iPhone or check for app updates.
- Force closing is different from restarting your phone — it only stops one app, not your entire device.
How to force close an app using the app switcher
The app switcher is the screen that shows all your open apps as cards. To open it, swipe up from the very bottom of your screen and pause for a moment. On iPhone X and newer models (which don't have a home button), swipe down from the top right corner instead.
Once the app switcher is open, you'll see cards representing each app you have running. Find the app that's frozen or not responding. Press and hold on that app's card until a menu appears, then tap "Remove App" or simply swipe up on the card to close it. The app will shut down immediately.
After you force close the app, wait a few seconds before opening it again. This gives your phone a moment to free up memory and reset. Then tap the app icon on your home screen to reopen it normally.
What happens when you force close an app
When you force close an app, it stops running right away. Any unsaved work in that app — like a draft email or a partially filled form — will be lost. The app doesn't get a chance to save your progress because you're cutting it off, not closing it gracefully.
Your phone's data and settings are not affected. Force closing one app won't delete files, photos, or anything stored on your device. The next time you open the app, it will start from the beginning, as if you had just restarted your phone.
Some apps may ask you to log back in after a force close, depending on how they handle sessions. This is normal and not a sign that anything went wrong.
When to force close an app versus restarting your phone
Force close an app when only that one app is frozen or misbehaving. If Safari won't load a webpage, or Messages is stuck, force closing that specific app usually fixes the problem without affecting anything else.
Restart your entire iPhone if multiple apps are freezing, your phone is running slowly, or force closing individual apps doesn't solve the problem. To restart, go to Settings, tap General, then Shut Down. Wait a few seconds, then press and hold the side button until the Apple logo appears.
Restarting your phone takes longer but clears your phone's memory completely and gives every app a fresh start. It's a more thorough fix when force closing one app isn't enough.
Troubleshooting if an app keeps freezing after you force close it
If an app freezes again shortly after you force close it, the problem is usually with the app itself, not your phone. Check the App Store to see if an update is available. Outdated apps sometimes have bugs that cause freezing, and updates often fix these issues.
Open the App Store, tap your profile icon in the top right, and scroll down to see pending updates. If the frozen app has an update available, tap Update next to it. Once the update finishes, open the app again to see if the freezing stops.
If the app still freezes after updating, try deleting and reinstalling it. Press and hold the app icon on your home screen, tap Remove App, then Remove from Home Screen. Go back to the App Store, search for the app, and tap the cloud icon to reinstall it. This gives the app a completely fresh installation.
Why apps freeze and how to prevent it
Apps freeze when they run out of memory, encounter a bug, or lose connection to the internet. Your iPhone has limited memory available, and when too many apps are running at once, some of them may slow down or stop responding.
To prevent freezing, close apps you're not actively using by swiping them away in the app switcher. You don't need to do this constantly — your phone manages background apps automatically — but if you notice your phone slowing down, closing a few apps can help.
Keep your iPhone's software updated by going to Settings, tapping General, then Software Update. App updates also matter: check the App Store regularly for updates to the apps you use most. Both iOS updates and app updates often include fixes for freezing and performance problems.
Frequently Asked Questions
Will force closing an app delete my data?
No. Force closing stops the app but doesn't delete any files, photos, or information stored on your phone. You may lose unsaved work within that specific app — like a draft message or form you were filling out — but your phone's data is safe.
Is force closing the same as uninstalling an app?
No. Force closing temporarily stops an app from running. Uninstalling removes the app from your phone entirely. After you force close an app, it's still on your phone and will open normally the next time you tap it.
Can I force close multiple apps at once?
You can force close them one at a time in the app switcher. Open the app switcher, swipe up on one app card, wait for it to close, then swipe up on the next one. There's no way to close all apps at once, but closing them individually takes only a few seconds.
What if I can't open the app switcher?
If your phone is completely frozen and you can't swipe or tap anything, restart your iPhone instead. Press and hold the side button and either volume button until the power-off slider appears, then drag it to turn off your phone. Wait a few seconds, then press the side button again to turn it back on.
Do I need to force close apps regularly to keep my phone running well?
No. Your iPhone manages apps in the background automatically, and force closing apps regularly won't improve performance. Only force close an app when it's actually frozen or misbehaving. Constant force closing won't help and may actually use more battery by forcing apps to restart.
