Download f.lux 4.43

After a long series of betas, the stable release of f.lux version 4 has now been released. This program adjusts the color of the screen to the position of the sun. For example, the screen is brighter during the day and when the sun goes down the color becomes ‘warmer’. Not only is this calmer for the eyes, it could even help with sleeping problems. The program helps find your location on Earth so that it knows exactly when the sun sets. F.lux is available for Windows, Linux, macOS, iOS and Android. Below is an overview of the major changes made in version 4, followed by the changelog of the last few versions.

what’s new:

• Analyzes your displays to show you how bright they are to your body: adjust your backlight and watch!
• Bedtime mode: warmer light before bed gets you ready for sleep, and works with all kinds of schedules
• Disable by app (so you don’t forget Photoshop)
• Backwards alarm clock: reminder not to stay up late
• Presets to help adjust your settings
• Color filters for eyestrain and other uses
