I use it, and I like it, and I think it works. But I also think they should really try to publish a paper on it, proving it works to improve e.g. people's sleep quality.

It's free and not obviously harmful and has a plausible biological rationale, but if you think it may not work, it's easy to run your own self-experiment: stick it in a little randomized script and record when you go to bed for, say, 50 days and see. That's what I did with Redshift: http://www.gwern.net/Zeo#redshiftf.lux

basically its the old Microsoft adage that Apple somehow co-opted, embrace - extend etc etc. Apple implemented a feature for the next release of osx that does what f.lux does, knowingly.

Back in the olden days (System 7~8) Apple would actually buy out the third party tools they wanted to add to the OS (MenuClock, WindowShade, etc). Then Steve Jobs came back and they just started Sherlocking developers instead...

They also bought third party tools under Steve Jobs (e.g. SoundJam MP, now known as iTunes)

I use redshift[0] on my linux machines which I really like. Cyanogenmod has LiveDisplay natively which is practically the same thing unfortunately it works off off gps location and not manually editable lang/long. Both are really helpful. [0] http://jonls.dk/redshift/

On Linux I use the 'Negative' Compiz plugin. You can apply it on a window by window basis or desktop-wide. For both modes there are keyboard shortcuts (that's what makes it such a killer feature IMO). People find the screen weird when I enable the plugin but I'm a practical guy and this has saved my eyesight. I know you can invert colors in OSX but the effect is desktop-wide and you can't use a hotkey to enable or di…

I've been using this method for years. Very simple, and gets the job done. Most websites and desktop apps default to whites and off-whites which convert perfectly to blacks and off-blacks when enabled. Pocket, Firefox, and FBReader on my Android devices all have dark modes for reading on my mobile devices; takes care of all my use-cases!

That's my case too! On Windows I have to use other kind of workarounds. Dark styles on VS, stylization addons on Firefox, etc...

That reporting starts from the research links on the F.lux site which 1) don't really say what they they seem to think they say and 2) often conveniently hide behind paywalls. The F.lux team genuinely seems to care about human health yet they haven't bothered to write the equivalent of a three page term paper about what they're basing their work on the past 8 years. It's odd. Even in this thread (as in the other six…

Some people, perhaps against their better judgement, like to use screens even as they're getting closer and closer to sleep. Some even use screens in bed. The difference in harshness of a 5800K screen and a 2700K screen is quite easy to feel in an otherwise dark room, late in ones "day", and once you're used to the latter, it is very uncomfortable to look directly at the former. One of them feels better on your eyes…

To clarify, I was speaking to broader claims of people saying f.lux puts them to sleep like a baby and the f.lux authors themselves claiming it as a tool in the fight against cancer and acne.

Note that f.lux does not even claim to prevent eyestrain. The closest they come is this: "Our users say that f.lux prevents eyestrain." That's hardly science; in fact it's exactly how shady companies market vitamins.

Also, I don't know what "feels better on your eyes" means but I will point out that if 2700K screens felt better "in an otherwise dark room" then movie theaters would use them. You say "It's that simple!" but like most things, it's a little more complicated than that.

I use the KDE equivalent all the time. Really nice on web pages at night when they're bright white. Don't know if it's saved my eyesight but it has made things more pleasant at times. It's also really nice to be able to invert the desktop and then invert a single window (VLC) so colors are correct there.

I am one of the people who love the idea of f.lux. I use it and it makes my eyes feel a lot better and makes me feel sleepy at the right times. But the app itself is terribly broken, at least on El Capitan. Whenever I switch modes, the screen flashes the original blue colors---my impression is that even a few seconds of blue light can mess up melatonin production, so this is unacceptable, especially from an app that…

> It's time that we move on to an implementation that actually works. Android announced "Night Light" and Kindle added "Blue Shade" and iOS came in last with "Night Shift" so it appears everyone has. When F.lux put up affiliate links hawking Himalayan salt lamps and Swarovski crystals and used "cancer" as the 30th word in a press release, I didn't feel too bad hitting "uninstall" for the final time. So Long, and Than…

Only one of the three things you mentioned is comparable to F.lux: iOS Night Shift.

> Kindle added "Blue Shade"

Blue Shade is, unfortunately, an exceedingly half-assed implementation; I wouldn't be surprised if an intern wrote it over the course of a month or two. Unlike F.lux, (or Cf.Lumen on Android), it doesn't change the color temperature of the screen—instead, it uses the same naive implementation as apps such as Twilight or Lux, which is a semitransparent reddish overlay that causes black colors to turn red. Considering that Kindles are running a completely customized Android ROM, Amazon could have done so much better.

> Android announced "Night Light"

This is only for Google Play Books, and nothing else. [1]

That's not what that expression meant: https://en.wikipedia.org/wiki/Embrace,_extend_and_extinguish

Ehhhh, it's a grey area. They are definitely in the 'embrace' stage, but they're doing it on iOS, where f.lux doesn't really have a presence. You can argue that makes it different, or you could argue it's close enough.

Blue Shade is almost 100% un-fucking-usable. Its as though Amazon shipped it without a single person trying it out one time.

I struggled with flux on linux for a couple of years until I discovered redshift. It works flawlessly.
