Windows/Mac/Linux/iOS: Popular screen-dimming software f.lux is now available for jailbroken iOS devices. Install f.lux to enjoy gently adjusted brightness based on the time of day for easy-on-the-eyes computer use.
f.lux is a unique app with a unique take on adjusting your computer’s (and now iOS device’s) screen for maximum comfort. It adjusts the brightness of your screen based on the time of day. Middle of the day with full sunshine? The screen is bright and white. Late at night and the world is dark? The screen dims accordingly.
It’s tough to describe exactly how subtle and pleasant the effect is, but if you’re not a fan of how blindingly bright screens can be in the late evening f.lux is a pretty neat fix. Given that the iPad’s lowest brightness setting is still so bright it lights up a room like a television set, we’re looking forward to trying out the new iOS f.lux app this evening.
f.lux is free for all platforms but does, however, require a jailbroken iOS device. If you aren’t jailbroken, a similar feature called Night Shift is built into iOS 9.3.
