Adjusts the color of your display based on the time of day.

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.

I often burn the midnight oil. I've found this utility a real manna from heaven because it soothes my weary eyes and allows me to stay in front of my monitor for long hours. Thank you for having brought to late-night users such a great tool. Fariborz AMIRSHAHI - Verona (Italy)

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! :-)
