iCube is distributed via sideloading for iOS/iPadOS and tvOS. We recommend using SideStore to install the app on your iOS/iPadOS device. To install on your tvOS device, use Sideloadly. To enable JIT on iOS/iPadOS, we recommend using StikDebug.

iCube supports MFi (Made for iPhone) controllers, PlayStation DualShock 4, PlayStation DualSense, Xbox Wireless Controllers, and the Siri Remote on Apple TV. Touch controls are also available on iPhone and iPad. See the Controllers page for details.

iCube requires iOS/iPadOS 16.0 or later for iPhone and iPad, and tvOS 17.0 or later for Apple TV. For optimal JIT-less performance, we recommend newer devices like iPhone 16 or later, iPad (7th generation) or later, and Apple TV 4K (4th generation).
