F.lux 4.55 for Windows – screen color temperature app

F.lux is a free app that helps you sleep better at night. You can download it here.

F.lux is simple: it automatically adjusts your computer screen’s color temperature and brightness based on the time of day. It’s brighter in the morning and warmer, easier on the eyes at night. That means your eyes feel much more rested after a full day at the computer. Several versions are available. The Windows version is available on this page. If you want other versions, please use this link.

Using a computer is part of everyday life for most of us, and long hours in front of a screen can take a toll. Many people struggle with headaches and sleep problems due to screen time. F.lux helps with this. After using the program for about a week, we noticed a clear difference. For example, when we went to bed, we fell asleep significantly faster.

All in all, f.lux delivers what it promises. It’s a lightweight, straightforward tool that’s extremely effective. It’s completely free, so we see no reason not to give it a try.
