f.lux is a cross-platform computer program that adjusts a display's color temperature according to location and time of day. The program was designed to reduce eye strain during night-time use and reduce disruption of sleep patterns.
The program is available for Microsoft Windows, macOS and Linux. It is also available for 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 has called upon Apple to provide developer tools and to allow their application into the App Store. A preview version for Android is available.
Upon installation, the user can choose a location based on geographic coordinates, a ZIP code or the name of a location. The program then automatically calibrates the device display's color temperature to the time of the day, based on sunrise and sunset at the chosen location. At sunset, it will gradually change the color temperature to a warmer color and restore the original color at sunrise.
