InternalUI Builds

This is a list of known Internal UI builds. Unlike Internal Firmware, these builds are internal versions of iOS, used for testing and debugging the different features before deciding whether to release to the public.

What are Internal UI builds?
Internal UI builds are internal versions of iOS, watchOS, iPadOS and tvOS that have features that aren't in release builds. These builds are for internal use within Apple and are often found on PrePVT Prototypes. Internal UI builds often have experimental features and internal apps. You can learn more about internal apps here.

What is Desense?
Desense is a slimmed down version of Internal UI, that are used to do quality control. These builds have less apps installed. These builds are also less valuable because of the lack of apps. Desense builds have around 2 full pages of internal apps while regular Internal UI builds often have 3 or more pages of internal apps. Additionally, these builds may contain diags.
