f.lux overview

f.lux makes the color of your computer's display adapt to the time of day, warm at night and like sunlight during the day.

Ever notice how people texting at night have that eerie blue glow? Or wake up ready to write down the Next Great Idea, and get blinded by your computer screen? During the day, computer screens look good - they're designed to look like the sun. But, at 9 p.m., 10 p.m., or 3 a.m., you probably shouldn't be looking at the sun. It's even possible that you're staying up too late because of your computer. You could use f.lux because it makes you sleep better, or you could just use it just because it makes your computer look better.

Tell f.lux what kind of lighting you have, and where you live. Then forget about it. f.lux will do the rest, automatically.

What’s new in version 42.1

Updated on Sep 24 2022

  • Apple Silicon support
  • Support for DCI-P3 wide-gamut displays: now these screens look much better, and should match sRGB colors. Previously, they looked a bit greenish and oversaturated, but now they look better than standard gamut displays.
  • Darkroom fix on M1/Apple Silicon
  • Sparkle updater at v1.24.

Will this work on an M1 Macbook Air when connected to a single monitor?

It's kinda frustrating because Mac has almost the same built-in feature (I can't remember exactly...something from sunset to sunshine) Maybe it still useful with older Macs

It helps at night, but every morning it switches the appearance on Mac back to "light mode" when I always have it on dark mode. Super annoying.

f.lux is great but I'd like it more if I could push its settings further: I complement it with a few launch agents that switch the color temperature of my monitor in the morning to blue and in the evening to orange. Of course, the colors of the evening are not meant to be realistic but soothing to the eye.

I am in the process of exploring other options as f.lux repeatably load new listings into my login items in my user preferences, disabling previous ones that have to be removed manually. Too bad as other than that I like it.

Loved this app for years. But I added a second monitor, and f.lux only works on the primary display. Now that Apple has added Night Shift to the OS that it will suffice.

The orange light is too dark and uncomfortable for the eyes. Lack of options for manual brightness controls.

Very useful application in order to save your eyes:) The screen is set up for your needs. You can quickly adjust or provide any necessary changes. Recommend for those who uses Mac all day long.

This would be the perfect app if adding the features of the old Shades! I've refrained from using f.lux for years just because I can't find a Shades equivalent, compatible with it...:-( So Mr Dev, if you ever read this: please add an additional dimming feature with configurable shortcuts (+ and -) and I'll worship you! :-)

f.lux does take some getting used to. However you can adjust it to suit your own idea of what a comfortable color shift is for nighttime. I've been using it happily for years. Now that Sierra has it's own night shift I guess I'll get around to trying it eventually. But the Apple version, as usual, cannot be customized. As is usual with Apple, it's a take it or leave it proposition, when you have any choice at all, which you often do not. At least with NightShift you can ignore it. The only drawback to f.lux I've found is that it's a bit difficult to understand how to set the parameters. I don't get the point of the bedtime settings.

I couldn't get used to this app. The display adjust colors only irritates. Is it a matter of time?

Very nice app for my eyes! I often change my working place, when the sun is bright it can adjust the display colors according to the daylight. Especially, I like the warm colors in the evening. F.lux helps me to add productiveness to my working day.
