A good many iPhone users who have recently updated to the latest iteration of iOS have complained about the random app crashing problem. However frustrating this issue may seem to be, it is easily curable. So, there is nothing to worry about it. Try out these 8 most effective tips to fix apps crashing on iPhone after iOS 18 update issue.

The better way to deal with an issue is to first find out the possible culprits upfront as it makes the job a tad easier. So, let’s get through it!

Why do iPhone apps keep crashing after iOS 18 update?

There are a few reasons your iPhone apps might keep crashing, freezing, or not opening after iOS 18 update. Your device could be running out of storage space, or you might have lost your Wi-Fi or data connection. Apps will usually warn you if these are why an app isn’t loading, but it might simply stop working or keep crashing instead.

If you notice your apps and games crashing after extended use, it could be because the phone is overheating. iPhones tend to compensate for overheating by throttling performance, which might cause the app you’re using to freeze or crash.

The biggest reason why iPhone apps keeps crashing after iOS 18 update is the lack of compatibility. If the app has not yet been updated or optimized to work with iOS 18, it will face numerous issues like unresponsiveness and crashing. Though a software bug and a miscellaneous glitch are also responsible for the problem. Been there done that; I have found a few workable solutions to get rid of this annoyance as and when it raises its head.

How to Fix Apps crashing on iPhone After iOS 18 Update

1. Force Quit the crashing Apps

You can try force-closing an app if it freezes or crashes. If the problem is due to an occasional software glitch, the force quit will resolve it straight away.

On iPhone with Face ID: Swipe up from the home bar and hold along the middle of the screen. After that, swipe up on the app cards to force kill all the open apps.
On iPhone with Touch ID: Simply double-press the Home button to bring up the app switcher. Then, swipe up the app cards to kill all the running apps.
Now, launch the app to check if the issue is gone. If you have gotten the better of the problem, there is a good chance that a random glitch was spoiling your party.

2. Update the Apps

If you haven’t updated the apps for a long time, I suspect it’s nothing but the outdated version that is causing the issue. Aside from triggering the frustrating crashing issue, an outdated version also causes out-of-the-blue crashing, rapid battery drain, and terrible sluggishness. Not to mention, it also makes an app more vulnerable to hacking. That’s the reason why it is always better to keep apps updated.

To make sure all your apps are up-to-date. Open the App Store and tap your Account Icon in the upper right-hand corner of the screen. Scroll down to the list of your apps with updates available.

Tap Update All at the top of the list to update all of your apps at once.

Once the update has finished, check to see if the problem is resolved.

3. Restart Your iPhone

Did you try turning it off and on again? Turn off your iPhone, let it cool down, turn it on again, and see if the app crashing issue persist. That’s all it sometimes takes, especially if your app is crashing because the phone is overheating.

Hold down the side button and either of the volume buttons until you see the power off slider. Drag the slider from left to right to turn off your iPhone. Wait a few minutes and then hold the side button until you see the Apple Logo on the screen.

4. Declutter the Apps

Another viable solution that you should try is to clean up the problematic apps. If the apps have been cluttered, decluttering could fix them.

Wondering how to clean up apps? Well, you can dive into the Settings of a respective app and look for a way to clear the storage. These days, most apps offer a hassle-free way to clear the storage. So, there shouldn’t be any pain in wiping out the redundant data and retrieving the precious storage.

5. Update Software

One of the most common reasons why the apps crashes is that the iPhone’s software is out-of-date. And in this scenario, going for the software update is always the best way forward.

Ensure that your iPhone has around 50% battery and is connected to a stable Wi-Fi network. If the battery is low, connect your device to a power source and allow it to charge up to 20%.
After that, go to Settings -> General -> Software Update. If an update is available, install it. iOS updates always contain bug fixes, so with few exceptions, it’s always a good idea to update your software. If your software is already up-to-date, move on to the next step.

6. Delete And Reinstall the Apps

If your apps keeps crashing after iOS 18 update, it’s time to put the old “unplug it and plug it back in” philosophy to work. A lot of the time, you can fix the crashing apps by deleting them from your iPhone and downloading them fresh from the App Store.

To delete an app, press and hold on the app icon on the Home screen until the quick action menu appears. Tap Remove App -> Delete App -> Delete to uninstall the app on your iPhone.

Next, open the App Store, tap Search at the bottom of the screen, type the name of the app you just deleted in the search box, and tap the cloud button to download it again.

7. Reset All Settings

There isn’t a magic bullet that fixes all software problems on iPhones, but the next best thing is Reset All Settings. Reset All Settings restores your iPhone’s settings to factory defaults, but it doesn’t delete any of your apps or personal information.

To reset all settings on your iPhone, go to Settings -> General -> Transfer Or Reset iPhone -> Reset -> Reset All Settings, enter your passcode, and tap Reset All Settings.

8. Last Resort: Restore Your iPhone As New

If your apps keeps crashing after iOS 18 update, you probably have a software problem that can only be fixed by restoring your iPhone. Unlike Reset All Settings, an iPhone restore erases everything from your iPhone. The process goes something like this:

Simply, connect your iPhone to your computer using a USB cable -> launch iTunes/Finder -> Select your device.
Next up, back up your iPhone. Once the backup is done, hit Restore iPhone and then follow the instructions to set up your device from the scratch.
