Install custom enterprise apps on iOS, iPadOS and visionOS
Find out how to install and establish trust for custom apps that your organisation creates.
This article is intended for system administrators for a school, business or other organisation.
Your organisation can use the Apple Developer Enterprise Programme You must establish trust for these apps before you can open them.
Apple recommends using a Mobile Device Management (MDM) solution to distribute the apps. Apps installed this way are managed, trust is automatically established and it doesn't require a user to manually trust the developer.
You can also install apps from a secure website that your organisation operates. If you manually install an app, you must also manually establish trust.
Establish trust for developers of manually installed enterprise apps
When you first open an enterprise app you’ve installed manually, you’ll see a notification that the developer of the app isn’t trusted on your device, and you won’t be able to open the app. Tap Cancel, then continue to the next step.
Tap Settings > General > VPN & Device Management.
In the Enterprise App section, tap the name of the app developer.
Tap Trust "[developer name]" to continue. In iOS 18, iPadOS 18 and visionOS 2 and later, tap "Allow & Restart" to proceed with establishing trust. In earlier software versions, tap Trust to establish trust.
After your device restarts, follow the onscreen instructions to complete the process and trust the developer.
After you trust this developer, you can manually install other apps from the same developer and open them immediately.
After you’ve verified an app for the first time, your iPhone, iPad or Vision Pro must re-verify the app developer’s certificate periodically to maintain trust. If you can't reverify, you may see a message that verification will expire soon.
Revoking trust for an app developer
When you establish trust for an app developer, they remain trusted until you use the Delete App button to remove all apps from the developer.
If the manually installed app is not verified
You must be connected to the internet to verify the app developer's certificate when establishing trust. If you're behind a firewall, make sure that it's configured to allow connections to https://ppq.apple.com. If you aren't connected to the internet when you trust an app, the device displays "Not Verified" instead. To use the app, connect to the internet and tap the Verify App button.
