Adjusts your computer's display to adapt to the time of day
I'm not wide awake before I go to sleep.Cons:
It's not possible to do design work with a blue light filter
Honestly, if I was to buy a new computer, this is the first thing I would download.
Although Apple and Google have integrated blue light filters into their operating systems, they still haven't matched the capabilities that f.lux offers. f.lux gives you more control over the filter strength and once setup, you don't need to touch.
Helps me sleep!Cons:
To easy to over ride and ‘cheat time’
Working almost all of the time and every night, on my computer, I find f.lux really helps me with winding down and preparing for sleep . The option to disable is great when I need it , however rather than creeping in like the filter does normally, it’s accellarated and comes in too quick becoming a distraction which leads me to go for the disable option again, being on Mac it does mean I notice the time a little more but it’s an hourly disable and another hour of bright white light keeping me awake . Quarter of an hour or half hours would be beneificial as well.Dave Clissold has used this product for one year.
Helps my eyes on a long computer stintCons:
If you forget you have it on and doing colour-sensitive work
I've been using f.lux for about 4 years and I love it. I now hate using a screen without it as I find it too harsh. I like that it auto-adjusts depending on time of day, environment etc. but you also have the flexibility to change settings yourself to make it comfortable.
It’s like Apple’s Night Shift feature...but on steroids! The temperature adjustability settings are powerful and scheduling works perfectly!Cons:
There a preset settings there - I wish the benefits of those settings or the reasons why they were chosen were clear. They seem arbitrary.
Really great app. Super minimal and straight forward experience. Once opened, the app works from the top menu bar of macOS. There are a ton of adjustments you can make from there. You can chose from one of the preset settings or you can customize your own settings until you’re comfortable. Once you do, you never have to worry about the app again. Your eyes will be saved, and on top of that you might even help other people out as well because when f.lux kicks in, people notice and ask me where they can download it from. So I definitely recommend this app, especially to anyone who works at night!
P.S. Feature request: a shortcut button that allows me to view my screen normally, while I’m holding those buttons down. I’m a designer, so colors are important to me but I don’t want to have to open the app, disable f.lux and then reenable it again. Just quickly/temporarily turn it off, and once I let go of those buttons it turns back on.
Easy to set upCons:
Works well with external displays on Macs, but not on Linux
I have been using this since it first showed up on Product Hunt. It's probably my most used 'app' even though I barely ever interact with it. Once I found my optimal settings, I don't think I've opened the app itself more than a handful of times. It works as advertised most of the time. The only time I've had issues is when using it on external displays with Linux. Since it's my secondary device, it's not been much of a problem though.
Easy set-up, works well, reminds me to go to sleepCons:
Non expect the usual effects of changing saturation of your screen.
Love the tool, you set it up once and works well. Easy to turn on & off when you want to. It also reminds me to go to sleep when it's late at night and i'm not concentrating on the time.Justin Plagis has used this product for one year.
Transitions almost perfectly!Cons:
Been using f.lux consistently since my friend recommended it to me. Great thing about it is that
- It lets you adjust the color temperature if their default settings don't work, but in most cases the default settings are spot on
- It has 3 presets and allows you to have custom colors
Generally its a great product so much so I didn't switch to the default mac app to adjust color temps
It's so good that I forgot I was using it. I have never turned it off since. :) Try it!Cons:
Maybe when doing design work, it could interfere with the perception of colour, but I have tried it while photoshoping, and it's no problem.
First started using it two or three years ago through an article in https://www.lifehack.bg/.
Saves my eyes.Cons:
Can't really complain if it actually saves my eyes.
Been a user of Flux for a very long time now and I can't think of a better alternative.
You probably have night shift on your Mac already, but f.lux does it better.Cons:
f.lux knows what your eyes like, more than you do
I really enjoy their "set it and forget it options" so I don't have to interact with the settings on the daily basis.Cons:
So far the developer is spot on and I have no complaints. :)
This product truly helps me throughout the day and it really helps eye strain.
feel better when looking at the screenCons:
some actions may make the screen switch from yellow to white quickly
It is a really good application to protect my eyes

Good for your eyesight and all you have to do is set and forgetCons:
Videos, images etc. might not be as accurate due to change in colour, but f.lix can be disabled for a short while at a time.
All round great product
Tells you when sunset is, when you are going to wake up (how many hours); adjusts monitor brightness perfectlyCons:

Better for the eyes as it filters out harmful blue light.Cons:
A problem if there is a need to view true colours
