InternalUI Builds

This article discusses software internally used by Apple. Acquiring a copy without Apple's consent is illegal and may result in being scammed. Engaging in illegal activity is not condoned. This information is provided for educational purposes only.

This is a list of known Internal UI builds. Unlike Factory Firmware, these builds have UI, like normal iOS builds.

What Internal UI builds Are

Internal UI builds are iOS, watchOS, iPadOS and tvOS builds that have features that aren't in normal builds. These builds are for internal use within Apple and may be found on 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. 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.
