Designed to help late-night computer users save their eyes, F.lux for Mac provides a softer and gentler backlight for the screen by helping the display adapt to the time of the day.

F.lux for Mac functions flawlessly, although we did have some difficulty finding it once we had closed it the first time. Once it is running, the only place it will be accessible is as an icon in the status bar at the top of the screen. It does not show in recently-used apps or the sidebar, and it does not reopen if you click on the icon in Finder. It does allow you to set your own level of brightness and has two options for fade time, but a slide bar for fade time would be a nice addition. On the whole there were no problems with the installation or function of the app, but additional (or easier) access would make it a much better product.

F.lux for Mac offers a great solution for people who work on computers for long hours. Once you get it installed correctly, it will change your screen automatically, and you will probably never know it is there.

"You can't set the time you want it to work"

misssbb May 11, 2017 / Version: f.lux 39.94

2017-05-11 00:55:15 | By misssbb

Pros

It really does dim the screen and changes the color so that it's very soothing and easy on the eyes. I love how it does that.

Cons

You can't have it turn on when you want it to, it goes by the time of sunset in your geographical location. When it doesn't get dark outside until 8pm, the screen doesn't begin to dim until then. Sol if you need to go to sleep at 9pm, it won't begin to work early enough for you to do that.

What passes for customer service is so bad that it's useless, so if you have a roblem you're on our own. They do have a forum, however, the person who was on the night when I had a question about changing the time when it started to work was so condescending and outright contemptous that it was a horrible experience.

There allegedly is a way to change the "on" time, but it involves resetting the latitude and longitude and that's above my paygrade.

Summary

It really works and if you're KK with being unable to customize the on and off time, you'll be very hppy with it.

I just got the Windows 10 Creator's update that allegedly has something just like this included, but good luck finding it. When I finally did and set it up (you can customize the settings), it made no discernable difference at all.

Just so you know, that update disables f.lux. I'm going to download it again - fingers crossed!

"Simple and Effective"

zindin8 September 06, 2016 / Version: F.lux 36.4

2016-09-06 07:34:45 | By zindin8

Pros

Works automatically in the background
Changes effect based on lighting and time

Cons

none that I can think of

Summary

This was my essential jailbreak apps on my iPad 4. Once you use it once, you will never want go without it. If you can, support the developer for their great work.

"Great for reducing eyestrain"

connectionfailure September 24, 2015 / Version: F.lux 34.3

2015-09-24 00:25:03 | By connectionfailure

Pros

Ever get that sore feeling behind or in your eyes after too much screen work? That's the bluish light from your monitor. Also this can keep you awake because your brain thinks that's daylight. This can fix both of those.

Cons

The Flux team is quite interested in making a time-based app that changes according to where you are and what time it is. Sometimes it's hard to make it do what you want because of that feature.

Summary

Just get it and try it out!

"Great app, no more sleepless nights!"

piraat.flappie.9 January 12, 2015 / Version: F.lux 30.1

2015-01-12 15:49:15 | By piraat.flappie.9

Pros

works without having to do anythuing after install and adding a city. simple and very affective.

Cons

I cannot find anything wrong. I do play a game on facebook and at night it is a little hard to see the true colors, so I can disable easily for one hour or I adjust my eyes after a few minutes and then it's okay too.

Summary

I recommand this app to anyone that has sleepless nights, and also I tell them to install it on their phone and tablet..because it's the blue light on all those machines that keeps you awake during the night.

"Costs a little RAM...but very worth it!"

shacoca October 19, 2013 / Version: F.lux 23.0

2013-10-19 12:01:23 | By shacoca

Pros

Works as advertised!

Cons

You'll sacrifice some RAM. Of course, you can always turn it off if other memory intensive apps complain.

Summary

A little memory hit is worth the benefit of this wonderful little app.

"Works great on Macbook Retina"

gurnx May 12, 2013 / Version: F.lux 21.0

2013-05-12 22:59:57 | By gurnx

Pros

Works well. Easy to configure.

Cons

No version-numbered downloads. Developer's site doesn't list release notes

Summary

Easy to install & configure. Developer's site is quite informative about app configuration, there's lots more science to eye-strain than I realized. Apple's Macbook Retina display quality doesn't 'tire' my eyes as do normal displays so an app like this is quite helpful. Thanks for the app, it's nicely done.

In the future I hope the developer will make available some version-release notes and perhaps an 'advanced' feature set (allow multiple-monitor individual setup, auto-quit during morning hours, etc.)
