Internal UI

1This is a list of known Internal UI builds. Unlike NonUI, 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 DVT and PVTe 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 is used to do quality control. These builds have fewer 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.
