Quick answer
The most common causes are insufficient storage, a poor internet connection, an outdated iOS, or a failed download from the App Store. First check storage and connection, then restart the device and delete and reinstall the app. If the problem occurs with only one app, update it or wait for a fix from the developer.
How to recognize the problem
- The app closes immediately after tapping the icon
- Installation stalls at "Loading" or "Waiting" and doesn't progress
- The App Store shows an error when downloading or updating
- The app works for a few seconds then returns to the home screen
- The icon is greyed out or blurred and doesn't respond to taps
Most common causes
Not enough free space
An update or installation requires temporary space larger than the app itself. When storage is almost full, the download stalls or the app crashes on launch.
Unstable internet connection
A Wi-Fi drop or an active VPN during download can leave an incomplete package. Such an app may install but crash as soon as it tries to load data.
Outdated iOS or iPadOS
New app versions often require a newer system than the one installed. In that case, the App Store offers an old version or refuses installation.
Incorrect date and time
A wrong date or time zone fails the certificate check when connecting to the App Store, so the download reports an error.
Bug in the app itself
Some developers release a version with a bug that crashes on certain models. The problem then disappears only with a new update from the App Store.
Step-by-step fix
- 1
Check free space
Open
Settings > General > iPhone Storage(on iPadiPad Storage) and see how much is free. Leave at least 2 to 3 GB free for installation and updates. If space is almost full, delete unnecessary videos, old messages with attachments, or apps you don't use. - 2
Restart the device
A restart clears temporary memory and stops stuck downloads. On an iPhone with Face ID, hold the side button and one volume button, drag the slider and wait for the device to turn off, then turn it back on. On older models and iPads, hold the power button.

Check the connection and turn off VPN
Switch to another Wi-Fi network or turn Wi-Fi off and on in
Settings > Wi-Fi. If you use a VPN, temporarily turn it off inSettings > General > VPN & Device Managementor in the VPN app. If you installed a profile with custom DNS, check it in the same menu. - 4
Check date and time
Open
Settings > General > Date & Timeand turn onSet Automatically. A manually set wrong date is often the cause of an error when connecting to the App Store. - 5
Update iOS and the app
Open
Settings > General > Software Updateand install the available version. Then in the App Store, open your profile in the top right corner and find the problematic app in the list of available updates. - 6
Delete and reinstall the app
Before deleting, check whether your data is saved in the app account or in iCloud, because deleting removes local data. Hold the app icon, choose
Remove App, thenDelete Appand confirm. Then find it in the App Store and install it again. - 7
Check restrictions and content
In
Settings > Screen Time > Content & Privacy Restrictionsand inSettings > General > VPN & Device Management, check whether installation is blocked by a profile or restriction. On a device managed by your employer, MDM policies may block installation. - 8
Reset network settings
If the error repeats only during download, open
Settings > General > Transfer or Reset iPhone(on iPadSettings > General > Transfer or Reset iPad) >Reset>Reset Network Settings. This deletes saved Wi-Fi passwords and cellular settings, so enter them again afterward.
If nothing helped
Check whether the problem occurs on one or all devices with the same Apple ID. If the app crashes only on your device but works on another, the cause is usually local data: delete the app, restart the device and install it again. If it crashes on all devices, it's likely a bug in the app itself, so check the developer's page and reviews in the App Store. As a last resort, you can make a backup in iCloud or on a computer and only then consider restoring the device to factory settings. Don't try to install apps outside the App Store via configuration profiles, because such installations are not verified and can compromise your data.
How to prevent it
- Regularly update iOS and apps from the App Store
- Keep at least 2 to 3 GB of free space on the device
- Don't interrupt downloads or turn off Wi-Fi during installation
- Check that date and time are set automatically
When to call a professional
If the problem occurs on multiple devices with the same Apple ID, if the device is managed by your employer, or if resetting network settings doesn't help, contact IT support before restoring the device to factory settings.

Why does the app crash immediately after launch?
Most often due to an incomplete download or a version incompatible with the installed iOS. Before deleting, check whether your data is saved in the app account or in iCloud, then delete the app, restart the device and install it again from the App Store.
Will I lose data if I delete the app?
Local data on the device is deleted. If your data is saved in the app account or in iCloud, it will be restored when you sign in again. Check this before deleting.
Why does installation stall at "Waiting"?
The device is waiting for a connection, space, or a queue in the App Store. Check Wi-Fi, free up space and restart the device, then start the download again.
