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 9PM, 10PM, or 3AM, 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.
f.lux makes your computer screen look like the room you're in, all the time. When the sun sets, it makes your computer look like your indoor lights. In the morning, it makes things look like sunlight again.
Tell f.lux what kind of lighting you have, and where you live. Then forget about it. F.lux will do the rest, automatically.
- macOS updated to version 39.94
- f.lux can go warmer than 3400K now, down to 2700K. Or even 1200K if you really want it to.
- Support for color profiles from a hardware calibrator
- Movie mode. This setting warms up your display, but it preserves shadow detail, skintones, and sky colors better than f.lux’s typical colors. It lasts 2½ hours, which lets you watch most feature films
- Disable until morning, for late-night crunch mode
- A new “darkroom” mode, which inverts colors and gets very red
- A map to help you find your location
- Hotkeys to dim your display (Alt-PgDn, Alt-PgUp) late at night, so desktop users can dim too
- A hotkey to disable/enable f.lux quickly: Alt-End
- If you have a laptop, f.lux gets warmer when your backlight dims, like an incandescent lamp
- A simple schedule for Philips Hue, so you can f.lux your house
