    Pros: 

    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.

    Pros: 

    Easy to set up

    Cons: 

    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.

Flux is one of my favorite finds on Product Hunt so far. I love the moment my screen dims at ~5:30pm. So relaxing.

It helps to understand the science. Blue lights suppress melatonin, which keeps you from going to sleep when you want to. This is why staring at screens before bed = no good. F.lux works by filtering out blue light. You get a red hue to your screen which takes getting used to, but it seriously makes it easier to go to bed if you're using your computer late at night. There's a similar Android app as well, that I highly recommend. Game changer.

Just remember to disable it if you're doing design work with color. 😅

I've been using f.lux for so long, it's hard for me to imagine life without it.

After using this for sometime, I can barely look at other screens now. Must-have for night-owls
