When using the app on an iPhone / iPad, there are cases where the app crashes suddenly while using, and the app crashes and returns to the home screen.
Even if the app crashes is not a problem, there are cases where it crashes repeatedly and interferes with the use of the app.
This article will explain when an application installed on iPhone / iPad suddenly crashes / repeatedly crashes.
Action 1: Quit all background apps
It is possible that a particular app suddenly crashes due to many apps running in the background.
Therefore, please close all apps running in the background and see if the problem is solved.
To quit an app running in the background, follow the steps below.
Display the home screen, swipe up from the bottom edge of the screen, and stop your finger in the center. For iPhone / iPad equipped with the home button, press the “home button” twice quickly.
- When you see the list of background apps, swipe up on the app preview to exit.
- Follow the same procedure to exit all apps.
After closing all background apps, launch the app that has the problem and see if it crashes. If the problem persists, proceed to the next solution.
Action 2: Restart your iPhone / iPad
The app may frequently crash due to a temporary malfunction in iOS or iPad OS.
If the cause is a temporary system malfunction, restarting the device is often the solution.
Therefore, please restart your iPhone / iPad once and see if the problem is solved. Follow the steps below to restart your iPhone / iPad.
- iPhone X and above: Press and hold “Side Button” and “Volume Adjustment Button” simultaneously, and drag the power off slider. When the power is turned off, press and hold the “side button” to start it.
- iPhone 8 and earlier: Press and hold the “Side Button” and drag the power off slider. When the power is turned off, press and hold the “side button” to start it.
- iPad (without home button): Press and hold the “side button” and “volume control button” at the same time and drag the power off slider. When the power is turned off, press and hold the “side button” to start it.
- iPad (with home button): Press and hold the “top button” and drag the power off slider. When the power is turned off, press and hold the “top button” to start it.
After restarting the device, start the app and check if the phenomenon of falling occurs.
If the app suddenly crashes and you can no longer operate your iPhone / iPad, try a forced restart. To perform a forced restart, follow the procedure below.
For iPhone 8 or later
- Press the “Volume Loud Button” once.
- Press the “Volume low button” once.
- Press and hold the “Power Button” until you see the Apple mark.
For iPhone 7
- Press and hold the “Power Button” and “Low Volume Button” simultaneously until the Apple mark appears.
For iPhone 6 or earlier
- Press and hold the “Home Button” and “Power Button” simultaneously until you see the Apple mark.
For iPad
- Press the “Volume Loud Button” once.
- Press the “Volume low button” once.
- Press and hold the “Power Button” until you see the Apple mark.
After the forced restart of the device is completed, please check if the app works properly. Try the following workarounds if your app still crashes frequently after restarting your device.
Action 3: Secure free storage space
The app may frequently crash due to insufficient free storage space on the iPhone / iPad.
Most apps use cache and app data, so running out of free space can cause crashes.
Therefore, check the free storage space of the device, and if it is insufficient, secure the free space. To check the free storage space, follow the procedure below.
- Open the “Settings” app.
- Tap “General.”
- Tap “iPhone / iPad Storage”.
Check the used space and free space in the “Used” item. The free storage space should be at least 10%.
If there is not enough free storage space, delete unnecessary images, videos, music, and apps to free up space. You can check the data that is used frequently on the storage screen.
When you have enough free storage space, start the app and check if the operation has improved. If you still have enough free space and the problem still occurs, proceed to the next solution.
Action 4: Update the app to the latest version
There are cases where the app suddenly crashes or frequent crashes, and the operation is not stable due to an old version of the app and a defect.
The app is automatically updated by default on the iPhone / iPad, but it may not be updated automatically unless manually updated or connected to Wi-Fi.
Therefore, please open the App Store to see if any app updates are available. Follow the steps below to update the app.
- Open the “App Store” app.
- Tap the “Profile Icon” in the upper right.
- If there are updates, tap All Updates.
If you want to update only a specific app, tap the “Update” button.
After updating the app to the latest version, restart the app to see if the crash issue has been resolved. If it is already the latest version, proceed to the next workaround.
Action 5: Limit content and privacy
There may be cases where certain apps are frequently dropped due to the screen time function of the iPhone / iPad limiting the operation of the app.
Therefore, please disable the content and privacy restrictions if screen time is enabled. To disable content and privacy restrictions, follow these steps:
- Open the “Settings” app.
- Tap “Screen Time”.
- Tap Content and Privacy Restrictions. If “Turn on screen time” is displayed, screen time is disabled, and you should try another workaround.
- Toggle the “Content and Privacy Restrictions” switch to “Off”.
Launch the app to see if it works better once you’ve disabled the screentime content and privacy restrictions.
Action 6: Perform a software update
Due to an old version of iOS or iPad OS, there are cases where the app’s operation is not stable and suddenly drops.
Therefore, run a software update to ensure your system is up to date. To execute the software update, follow the procedure below.
- Open the “Settings” app.
- Tap “General.”
- Tap Software Update.
- When the new update information is displayed, tap “Download and install.”
- If the passcode entry screen is displayed, enter your iPhone / iPad passcode.
- Tap “Install Now.”
Launch the app and see if it works after performing a software update to update your system to the latest version.
Action 7: Reinstall the app
There may be cases where the app does not work properly and crashes due to corruption of the app or the related data of the app.
Therefore, please uninstall the app and then reinstall it to see if the problem has disappeared. However, keep in mind that uninstalling the app will delete the data in the app.
Follow the steps below to reinstall the app.
-
- Press and hold the “Problem App Icon” on the home screen. If you don’t see the app icon, swipe to the rightmost screen to open “App Library” and look for the app icon.
- Select Remove App from the context menu that appears.
- Tap “Delete” when the warning is displayed.
- When the deletion is complete, open the “App Store” app.
- Search by app name to display the app page, then tap “Get” to install.
If you can reinstall the app, make the necessary initial settings, and check if the crash issue has been resolved.
Action 8: Reset all settings
There may be cases where certain apps are frequently dropped due to a problem with some settings on the iPhone / iPad.
Therefore, please reset all the settings of the iPhone / iPad once to see if the problem is solved. Even if you reset the settings, the data will not be deleted, but all the changed settings will be returned to the initial state.
To reset all iPhone / iPad settings, follow the steps below.
- Launch the “Settings” app.
- Tap “General.”
- Tap “Reset.”
- Tap “Reset all settings.”
- Enter your iPhone / iPad passcode.
- When the confirmation pop-up appears, tap Reset All Settings.
- Wait for the iPhone / iPad to restart.
After resetting all the settings, launch the app with the problem and see if it works better.
Action 9: Wait for a new update for the app
If only a particular app crashes frequently, the latest version of the app may be defective.
Therefore, try searching for users who have the same symptoms on search engines or Twitter.
If you suspect something is wrong with your app, it’s difficult for you to handle it, so wait until a new update for your app is available.
Action 10: Initialize iPhone / iPad
If the app still crashes after trying these methods, your iPhone / iPad system may have some irreparable problems.
If multiple apps frequently crash instead of a specific app, there may be a problem with your system.
If you suspect a problem with your system, consider initializing your iPhone / iPad. However, it is recommended to make a backup because the initialization will delete all the data in the storage.
Please also refer to the following pages for the procedure to initialize iPhone / iPad.
After initializing the device, install the app and see if the problem is resolved.
If multiple apps frequently crash even after initialization, the hardware such as storage may be physically damaged. If you suspect a hardware failure, consider requesting diagnosis and repair at your local Apple Store or Apple Support.
