Pros
Pro Free
As in price, not open source code.
Pro Can help sleep better
Helps provide better sleep for more energy during the day.
Pro Eases eye strain
Decreases color temperature at night, changing the normally fluorescent blue of an LCD monitor to a soft orange. Much easier on the eyes, especially in a low-light environment.
Pro Subtle transition
The transition from daytime to nighttime color modes takes an hour by default and will detect your current timezone, meaning that it will happen in the background at sunset, often without you noticing.
Cons
Con Non negligible processor ressources use
For such a tiny app, with a very limited function, idle most of the time, it actually is using non negligible processor ressources (frequently around 2% when not in use, and totalling more than Alfred, Dropbox or 1Password, for example).
Con Takes a while to get used to
After installing F.lux, the screen will look a lot more yellow. This takes about a week to fully get used to. You can ease into it by setting the color temps higher than the recommended defaults.
