Intro to content distribution for Apple devices
The most scalable way to distribute apps and books is to purchase them in volume through the Apps and Books section of Apple School Manager or Apple Business Manager. Apple School Manager or Apple Business Manager, and your mobile device management (MDM) solution, then work together so you can assign apps to your devices or users wirelessly, even if the App Store is disabled. All paid and free apps, and most books on the App Store and Apple Books, are eligible for purchase or download. Your organisation then owns these apps. Distributed books are owned by the user.
Apps purchased in volume can also be assigned, revoked and reassigned to devices or users in any country or region where the app is made available by the developer, enabling multinational distribution for your organisation. Developers can make their apps available in multiple countries through the standard App Store publishing process in App Store Connect. For this reason, purchases must be made in a country where volume purchasing is available in Apple School Manager or Apple Business Manager. For more information, see the Apple Support article Availability of Apple programmes and payment methods for education and business.
Note: In-app purchases and subscriptions aren’t compatible with volume purchasing, Managed Apps or Managed Apple Accounts. Developers may offer a separate full-featured version of their apps (sometimes as a Custom App) for education or enterprise customers that need to deploy apps at scale.
App sandboxing in iOS, iPadOS and visionOS
All third-party apps are “sandboxed” to restrict them from accessing files stored by other apps or from making changes to the device. Sandboxing is designed to prevent apps from gathering or modifying information stored by other apps. Each app has a unique home directory for its files, and that directory is randomly assigned when the app is installed. If a third-party app needs to access information other than its own, it does so only by using services explicitly provided by iOS, iPadOS and visionOS.
System files and resources are also shielded from the users’ apps. Most iOS, iPadOS and visionOS system files and resources run as the non-privileged user “mobile”, as do all third-party apps. The entire operating system partition is mounted as read only. Unnecessary tools, such as remote login services, aren’t included in the system software and APIs don’t allow apps to escalate their own privileges to modify other apps or iOS and iPadOS.
For more information, see Security of runtime process in iOS and iPadOS in Apple Platform Security.
App thinning
Managed Apps from the App Store, Custom Apps and Unlisted Apps for iPhone, iPad, Apple TV and Apple Vision Pro support app thinning, which downloads and installs only the specific version for the associated operating system, allowing faster downloads and reduced download volume.
Decide which app types you want to distribute
Before you distribute apps, decide which types of apps you want to distribute in your organisation. You can install more than one app type.
App Store apps: Apps installed from the App Store using Apple School Manager, Apple Business Manager, Apple Business Essentials or MDM are called Managed Apps. They often contain sensitive information, and you have more control over them than you have with apps downloaded by the user. For more information, see Distribute Managed Apps.
Custom Apps: With Apple School Manager, Apple Business Manager or Apple Business Essentials, you can buy Custom Apps tailored for the needs of your organisation. These apps, built by yourself or third‑party developers, are distributed to you privately. You can view them by turning on Custom Apps in Apple School Manager, Apple Business Manager or Apple Business Essentials. For more information, see Distribute Custom Apps.
Unlisted Apps: You can leverage Unlisted Apps to distribute organisation-specific apps. For example, if your organisation has an app they’ve created for staff, teachers, employees or contractors, you can publish it to the App Store and use a direct URL to download the app. These apps don’t appear in any App Store categories, charts, search results or other app-related listings. Unlisted Apps are considered hidden but not private and are accessible only with the direct link. For more information, see Distribute Unlisted Apps.
Proprietary in-house apps: Proprietary in-house apps are distributed to devices, not users. They require self-hosting and management of provisioning profiles and distribution certificates. For more information, see Distribute proprietary in-house apps.
Managed App types, how they’re purchased and more are listed below.

App Store apps | End user or organisation | General public | Everyone gets the same app. |

Unlisted Apps | End user or organisation | Limited internal or external audience | Everyone gets the same app. |

Note: You can also install apps on iPhone and iPad connected to a Mac through USB (or Apple TV devices paired through Bonjour) with Apple Configurator. For more information, see Configure devices with Apple Configurator for Mac.
Assigning apps and books
