The current version of Invisible: Controller for iOS is tested to work on all iPads running iOS 8 or higher. These include:
- iPad Mini
- iPad Air or Air 2
- iPad (2017)
- iPad Pro (9.7" and 12.9")
For the best experience, use a recent iPad Mini or a recent iPad with a 9.7" screen (Air 2, 2017 or Pro).
Older iPads may not run Invisible: Controller as well, especially if you run the app in an "always on" type installation (mounted in a wall or on a counter).
Invisible: Controller does not (yet) support iPhones or Apple Watch.
