Unlisted apps are published on the App Store but are not discoverable through public channels like search, categories, charts, or recommendations. They are intended for limited audiences, such as event attendees, research study participants, or specific employee groups. Access is granted exclusively through a direct link, which can be distributed as needed. Once an administrator in Apple Business Manager or Apple School Manager has the link, they can also acquire licenses for unlisted apps and distribute them to their organization. This method provides a balance between the App Store's trusted review process and controlled, non-public distribution.

A. Custom: These are distributed privately to specific organizations through Apple Business Manager or Apple School Manager, not via a direct link on the public App Store.

C. In-house: These are distributed entirely outside the App Store using an Apple Developer Enterprise Program certificate for internal employee use only.

D. Public: These are fully discoverable on the App Store through search, browsing, and recommendations, which is the opposite of the requirement.
