We’re happy to announce a new update to f.lux for Mac today.
This new version has been in progress for a long time. We’re sort of nervous and excited about it, because we tried so many things before we figured it out.
Quit old versions before running
The new version of f.lux makes a schedule just for you, so you can use a screen that knows when you sleep, as well as when the sun’s up. We found a way to combine your day with sunrise and sunset. Here’s how it looks:
f.lux now shows you when the sun’s up and helps you wind down for sleep.
With the new f.lux, your screen warms up to make things look better at sunset. But then later, around the time you would start feeling sleepy, we do a little more, helping you get to bed on time. We’ve even tried to time this second phase with your body’s natural release of melatonin. You may find you want a more moderate effect at sunset now, because the bedtime setting can be more intense.
It’s really easy to set up, and it looks pretty good too.
Usually, we try to make things visual and avoid using tons of numbers. But one number stood out so much that we had to put it up front.
How many hours of sunlight could you see with your current schedule?
A healthy circadian rhythm depends on seeing bright light while you’re awake, not just avoiding bright light before bed. Especially if you’re a night owl, this number is a super-interesting way to think about your day, and we hope it’s useful to you too.
To have all this new stuff, all you do is tell f.lux when you wake up:
We suggest some default colors for people in different situations. (For instance, you can now use f.lux if you work the night shift, if you wake up at 3AM, or if you live in Oslo.)
If you need to do color-sensitive work, now you can run at full brightness until just before bed, and then f.lux will wind you down just in time to sleep.
There’s even a way to sleep in on weekends.
As the day progresses, f.lux will move between its three light settings automatically. But because color perception depends on where you are, it’s kind of hard to predict how you’ll see colors at 11PM while sitting in your office at 1PM. We made this new interface so you can come back a few times (for a day or two) to set f.lux the way you like.
Thanks for using f.lux, and if you need help with the new features, please join us on our support page here: http://justgetflux.com/faq.html.
