    This is open source, while f.lux wants you to download a binary and run it constantly on your system.

    Very minimalistic and lightweight. Doesn't affect games (i.e. microstuttering) the way f.lux does (if you set it to Paused mode).

    CF.lumen - don't let your phone blind you! CF.lumen changes the colors of your Android device's display based on the position of the sun. With the default settings, your display will get a warmer tint (lower color temperature) when the sun is down, to look more like indoo.
