I have just come across F.lux. This app has been available for several years now so I am sure that some of my readers have heard of it, but it is new to me.
F.lux is a simple app that runs in the background. It manipulates the screen settings on your device so that they mimic the natural daylight in your area. In short, if you spend evenings (and early hours) sitting in front of a computer screen for any reason, F.lux will help you sleep better, by calibrating your screen’s brightness to the rise and fall of the sun in your location.
This is a pretty cool idea and given the many hours I spend in front of a computer I wish had heard of it years ago. But it’s not going to be as useful as some might think. The problem with F.lux is that if it perfectly mimics the sunlight at my location then it’s going to turn off my screen at sunset. I’m not sure that will be terribly useful.
Kidding aside, F.lux does adjust to night time by making the light warmer. I’m not sure what that means but I plan to find out tonight.
F.lux is available for Windows, OSX, and Linux. There’s no Android version, and while there is an app for the iPhone and iPad it will only run on jailbroken devices. This app offers the kind of hardware control that Apple usually doesn’t want to share – not with developers nor users. And that’s a shame because I would like to have this on my iPad.
Have you tried this app? What did you think?
