Install custom enterprise apps on iOS, iPadOS, and visionOS
Learn how to install and establish trust for custom apps that your organization creates.
This article is intended for system administrators for a school, business, or other organization.
Your organization can use the Apple Developer Enterprise Program to create and distribute proprietary enterprise iOS apps for internal use. You must establish trust for these apps before you can open them.
If you install an app by Mobile Device Management (MDM), trust is automatically established. If you manually install an app, you must also manually establish trust.
Apple recommends that you use an MDM solution to distribute the apps. This method is secure and doesn't require a user to manually trust the developer. You can also install apps from a secure website that your organization operates.
Manually install and trust an enterprise app
When you first open an enterprise app that you've manually installed, 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.
There will be a list of apps from the developer on the next screen and if they are verified. Tap to trust the app developer, then tap Trust to confirm your decision.
After you trust this profile, you can manually install other apps from the same developer and open them immediately.
After you verify an app for the first time, your iPhone, iPad, or Vision Pro must reverify 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.
