f.lux for Mac

24 March 2021

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

What is f.lux for Mac

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.

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

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.

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.

There's been a bug in the app for years that prevents full screen video viewing without it messing up. Flux blames Apple, but whatever the reason this makes this an app that's not that useful. Apple has built in a similar functionality to the latest MacOS. Looking forward to finally having something built in so that I can uninstall flux.

Flux is a "must have" for those who use a computer after sunset and have suffered the effects of digitally-induced insomnia. This app gradually dims the screen by blocking out the blue light so you don't want to do photo or video editing when it is active because your screen color will "sunset" but other than that there are no caveats. App is stable and reliable. I have donated to the developer.

Installed this app - wow, it is really great. I sometimes work with my computer at night with the light off and because of the difference between the darkness around and light from the monitor my eyes became sore. It was too annoying to change settings every now and then. This app has completely solved my problem.

I don't know how I did without this app for so long. The standard white point temperature of 6,500 Kelvin is way too blue and washed out for evening use.

The only minor complaint I have is with the "you're getting up in x hours" nag-ifications. We really need the option to disable those as I don't want a virtual mother telling me it's past my bed-time :P

It's a good app, but it makes the screen a bit too orange with the default settings. I've had to play around with it. I also wish it would work like iOS' Night Shift (yeah, I know it's a copy), which has better color and sets to sunrise and sunset, and not the time I wake up.

Great little app to reduce sleeplessness due to effect of blue light on diurnal rhythms. The only problem I have with it is its name. The official name should not have a "." in it as this indicates an extension in proper computer naming conventions. In addition, the actual app name is confused with several other apps named Flux, such as the popular web development app. I recommend that the creator of "f.lux" change the name to "F-lux" (or "Kelvin" or "NighShift" or "Nocturnal" or something else) to avoid the app being overwritten by MacUpdate Desktop and to follow a better naming convention. I actually like the name "Kelvin" since that is the scale used for color temperature, which is what this app alters.

I wish the developer would have left well enough alone. The most recent feature -- notifications of how much time is left in sleep -- clutters my screen in the morning and there's no way to turn it off. All I can say is "What were they thinking?" Since there's no way turn this dis-feature off, I'm tossing the most current update and using the older release. Also, the new colors are to red. I don't like them so I use "Classic f.lux" instead. Stop messing with something that works.

I don't understand what motivates the developer aside from benevolence—this app is so good I would gladly pay for it, and more than just a couple of dollars. As an inveterate night shift worker, I've used environmental light colors for years to maintain a regular sleep/wake cycle away from work. Finally I can do the same thing on my laptop.

The app is based on solid science and the interface is exceptionally polished. The ability to tweak settings is well thought out and incredibly useful. I tweaked the color temps, especially the default sunset color. The darkroom mode is something I hardly ever need (back in the day, I worked in darkrooms and had a home darkroom), but it's also great to have when one needs it. (Note: I do wish that that mode were tweakable.) The devs were smart enough to make f.lux disable itself when Photos is in use. [I haven't seen what happens if other color-dependent photo or art apps are in use.]

One of the best apps I've used, and I've been on Apple gear for three decades. Kudos to the devs!


Highly recommended

Feature request: 1. I can't set more than 3500K and less than 5000K for bedtime mode. Why? The only option is to set less than 3500 or 5000K (which means night mode is off and it's same as sunset). But I want to keep Sunset at 5000 and have bedtime mode a bit higher than 3500K. It doesn't allow me to do it. I am on custom colour option. 2. The application menu could have option to override the current mode till the next mode change. For example during night, I'd like to set the sunset mode manually. In the morning the the mode would change to daytime mode and continue to follow the schedule. This is useful in case I don't want to disable f.lux completely by changing to daytime mode, bur rather change to a more comfortable sunset mode. Thanks.

Can't really use it. Not sure if it's just me, but when the app changes to sunset- or night-mode, I get reddish screen. The colours become red tinted. I would expect to be able to adjust the colour change through RGB sliders or Gamma or something, or just be able to set the screen to get gradually darker. This app seems to decrease the G and B spectrum while leaving the Reds. Not effective way to prevent eyestrain, in contrary, my eyes ache after a few minutes, I have to close it. It's a great application and idea but what is with this red tinted colours. I have Mavericks, Dell monitor with proper ICC./ICM colour profile loaded in Display settings (colours are perfect by the way).

Simple and effective. I've tried many screen utilities over the years and this is the only one I've decided to launch on login. I had already discovered when using a tablet for reading that a warmer color scheme like "sepia" will make me fall asleep easier along with causing less eye strain. To see such an elegant solution for my Mac is wonderful. It may not be possible, but if this developer could implement f.lux functionality into an Android/iOS app then I'd buy it for sure.

The new version gives me problems every evening. I have the setting to "work late" - because that's what I do - and it kicks in properly. However, regularly at midnight it abruptly changes back to daytime colors, then goes down again, then up once more for a short peak. It really drives me crazy and "wakes me up". The last version did not have this problem - at least not for me.

The latest version of f.lux has some nice enhancements. In particular I like the ability to disable it on a per application basis so that, if I'm working in Photoshop, for instance, it will not kick in and distort the color space. The ability to customize the color used at night time is probably it's strongest feature. This enables me to set it to suit my preference rather than use the default settings. The new version takes a little time to tweak, given the new variables, sunset and bedtime, but it's well worth the effort.

I love this app when working at night. So much easier on the eyes than my iMac's default settings. My main problem with f.lux has always been remembering to keep it switched off when watching a movie or using graphics software. This update addresses that problem, allowing you to disable f.lux for the rest of the night rather than one hour, and also for individual apps: just select Disable from the f.lux menu and the current app will be excluded. I'd prefer to have an editable list of exluded apps in the preferences, but this is a workable solution.

Nifty little app that automatically color-shifts your computer screen for nighttime use. It's easy to turn f.lux on and off without quitting the program. It's both stable and polite. Since f.lux doesn't DIM the screen, I use it combination with the screen dimmer Shady. When dimming is off, your screen looks normal. Features I hope the developer will add: a setting for white LED bulbs; ability to change the color temperature to red to preserve your night vision; and an integrated dimmer (so I can use one program instead of two).

Excellent little app, and I tested a bunch of them before picking this as the best. Stable, easy to use, can dim your screen WAY down, and doesn't affect the screen brighteness or color at the brightest setting. Plus you can just switch it off to watch a movie, and keep your settings. I use it in combination with f.lux, which color-shifts the screen but doesn't dim it.

Great app! The only improvement I could hope for would be to add different durations for the dim effect (2 or 3 hours). For those having blinks if used together with Shades, you can instead use Shadeit! (version 1.1) which doesn't conflict with F.lux. ;-)

It's pretty much perfect for its purpose, and I really like the effect. Of course, it's subjective - I don't have brainwave scans or whatever, to prove that it's improving my computing experience at night - but I feel that it is. The only thing I would change is that the option to shift brightness and color tone gradually should certainly be on by default. You don't even notice it happening over the course of the evening, like the sun itself progressively going down. The default sudden-change option is jarring.

A piece of software that provides a feature that should be standard on every Mac and iOS device. I'm really pleased that it remains in active development. The only thing I wish it had was a built-in update mechanism.

Great idea, but terrible blurs and weirdness when scrolling or using the mouse, making it unusable. Which is a shame.

I love the idea and it's instantly soothing on my eyes. However enabling this app slightly makes OSX animations more choppy/jerky. Most noticeable by the increase trails on the mouse pointer.

I use f.lux every day...err...night. Can't imagine burning the midnight oil night after night to finish a project without it. Minimizes harshness of staring at a screen all night, lessens eye strain, while also allowing the brain to realize the sun as set. Another BIG PLUS is simply having the ability to dim the screen far past factory settings without going completely black, which is perfect for anyone working late with a significant other trying to sleep.

Very nice, but it would be MUCH more useful if you could specify times for each day when f.lux becomes active and when it stops being active. For example I work on the computer till about midnight, so I would like f.lux to start at about 10 pm. Right now it starts at 4:30 pm (as that's when the sun sets) - so I keep disabling f.lux for an hour several times. After an hour it jumps straight to deep red - which is shocking. It would be much better if you could choose a gradual change again. A partial workaround is to set the longitude to a few hours ahead - but then you have to set it back in the morning or you work with a red screen all morning. So in short: nice idea, implementation can be improved.

Love this beautiful little helper app. Can't live without it anymore. I encountered a small glitch from time to time, the occasional "daylight flash" here and there, but that doesn't really bother me. A couple of more features would be great. I would welcome a longer transition time that actually follows the sun, starting e.g. 30 minutes before sundown, and ending roughly at twilight's end. Also I would like to be able to have more options with regard to disabling the effect, e.g. for 1 1/2 or 2 hours, if you're watching a movie, or with some manual entry option. But that's all really secondary.

If I could choose only 5 utilities to have on my Mac Flux (formerly f.lux?) would definitely have to be one of them. Once you've used it for a couple days or well nights, because night is when it works it's simple magic, you simply can not go back to a normal colored screen. Such a simple, elegant idea to solve a big problem. I sleep much better now and have far less eye strain, totally addicted. The naming is a bit confusing, it used to be f.lux and there is another app for developing websites called Flux so I think the name should be changed to distinguish itself but this has no impact on the simple awesomeness the app does when the sun goes down. I think this may be my first ever 5-star rating on MU!

I've been using Flux for a while and like it. Never had a problem with it and works as advertised. That said, it would be nice if this update page would say what is new with this release. Went to the developer's site and there is no obvious version release page available. In addition, the "about Flux" feature doesn't tell which version it is. I apparently don't have the hitherto newest version, so may this has been added. At least with my version there are two transition states: fast (20 sec) and slow (1 hr). Seems an intermediate one would be good, say 20 or 30 minutes; perhaps that has come along in the updates.

I think the developer and Mac Update got their wires crossed. When I used the link on this page I got an old version of Flux. I had to go to the developer's web site to get what is apparently the current version, 12. As far as I can tell the version listed on this page, 13 doesn't exist.
