I just released F.lux for Ubuntu (fades your screens at night)

F.lux adjusts the color of your computer's monitor to match the time of day. It's warm at night and like sunlight during the day.

I've been using F.lux for a couple of months on OS X. The orange color at night looked a odd to me at first, but now I don't notice it.

F.lux can help you sleep better: http://www.stereopsis.com/flux/research.html

A similar program for automatically changing the color temperature, Redshift [1], was recently highlighted by Lifehacker and others as an alternative to the commandline-only XFlux, inspired by F.lux.

EDIT: One advantage Redshift has is that it automatically determines your lng/lat based on your current "home" location in the Clock applet.

Why is it only for Ubuntu? Or is it also runnable on, say, any GNOME setup?

I've been using flux and find it works as advertised on helping my sleep patterns. Thanks for your work on it.

I started using F.lux a month or so ago to help with insomnia. It's helped a lot, thank you for writing it.

I've been holding out on buying an iPad to read in bed, precisely because F.lux has helped me so much on OSX. Is there a flux equivalent for iOS? Is it possible to write one?
