The program is available for Microsoft Windows, macOS and Linux (except for Ubuntu 18.04 LTS). It is also available for Apple iOS devices, although it requires the device to be jailbroken. Apple has not allowed the application in its App Store due to its use of restricted developer tools. The developer briefly hosted an Xcode project on GitHub, allowing iOS 9 users to sideload the application onto their devices, but retracted it at the request of Apple. Following Apple's announcement of a similar function, called Night Shift, in iOS 9.3, the developer called upon Apple to provide developer tools and to allow their application into the App Store. A preview version for Google's Android system is available.
