You can manually add iOS apps to Jamf School from the App Store. When distributing apps purchased from the App Store, users must sign in with their Apple Account before the apps can be distributed. If you want to eliminate this step, you can purchase apps and books using Apple School Manager and assign the licenses to your users' devices instead. For more information, see Apps Purchased in Volume. Apps can be assigned to a device serial number on devices with iOS 9 or later.
