How to Fix Apps That Will Not Open on an iPhone
Learn how to fix iPhone apps that crash, get stuck and just won't open by force quitting or reinstalling the faulty app.
When an iOS app encounters a bug, it might behave in unexpected ways, crashing the moment it opens, not opening at all or getting stuck on the title screen. Force quitting the app and then restarting it usually solves the problem. If that doesn't work, delete and reinstall the app.
- Apps that don't support your phone's hardware or iOS version mightnot run correctly, if at all. Check the Compatibility section on theapp's page in the App Store to make sure your phone meets therequirements. Some app developers continue to offer old versions of apps for compatibility with earlier phones.
- Ifa developer doesn't update an app for new iOS versions, it might stopworking after an iOS update. In this case, contact thedeveloper or choose an alternative app.
Force Quit the App
Press the Home button twice quickly to open a list of recently used apps. Scroll side-to-side to find the app that's not working.
Swipe the malfunctioning app's page upward to remove it from the list, forcing it to quit.
Reopen the app as usual. After a force quit, an app reloads completely, rather than resuming from its last position. If the app again gets stuck, crashes instantly or won't open at all, restart your phone and this process. If the app still won't work, remove it from your iPhone and reinstall it.
Remove and Reinstall the App
Deleting an app from your iPhone erases all its saved preferences and data. Clearing out these materials often fixes apps that stop working after an update. Because you'll also lose your saved data in the app, you should only delete an app as a last resort.
Tap and hold the app's icon until the app icons start shaking. Tap the X on the icon's corner to delete the app.
Tap Delete to confirm.
Search for the deleted app in the App Store. Tap the cloud icon to reinstall the app. The cloud icon indicates apps that you've previously downloaded. Even in the case of paid apps, iTunes doesn't charge you again when you redownload an app or other content by tapping the cloud icon.
To see a list of apps that you've downloaded previously that aren't currently on your phone, open the Updates tab in the App Store, tap Purchased and choose Not on This iPhone.
Open the app as usual and set up the app's preferences from scratch.
