Is a colour temp change on our android display possible like with Redshift and F.Lux?

---

Came across F.Lux a while back and after installing it on my laptop tonight I remembered how huge a difference it makes to your eyes and sleep after you adjust to it.

F.Lux or Redshift (Linux's variant) reduces the colour temperature of screens to reduce the blue level, as when your eyes pick up blue light from any source, your body reduces sleep hormones (melatonin) and keeps you going as it believe's it's still daytime. Ever wake up throughout the night or wake up feeling groggy everyday? This might be why.

Here's a bit from the F.lux website:

"F.lux fixes this: it makes the color of your computer's display adapt to the time of day, warm at night and like sunlight during the day.

It's even possible that you're staying up too late because of your computer. You could use f.lux because it makes you sleep better, or you could just use it just because it makes your computer look better."

So what I'd like to know is if an app like this is possible on Android?

Something along similar lines was developed here: http://jsharkey.org/blog/2010/07/01/...un-and-profit/
But this sets the screen to only use one colour to display everything, be it red, blue, green, etc? but this effect is at the extreme end of the spectrum. If our phones could be tweaked to about 3400k when needed this could end up being a really useful app for all of us who stick our faces in front of our phones at night!

CyanogenMod has the Render Effect setting where you change the color temps to presets, but I haven't found an app that can do anything automatic like f.lux.

Do you know what this piece of software is called?

Does anyone have any interest in developing an app like this? just like the F.Lux software. I for one would be interested in purchasing/donating to it.

I think I stumbled across what you were talking about. 'Droid calibrator' it was named. Continuously crashed under non Galaxy S environments though, so that idea is out unless it could be modded somehow.

But yeah, does anyone have any other tips on existing software or have any interest in something like this also?

Bump this topic up! I just starting using F.lux today, and I'd kill for an Android version.

I wish i knew what it was called but my friend did have an app on his phone that changed the screens color. I assume this is what you want. Basically he had like 10 different widgets and each one tinted the screen that color.

That's a default feature of CyanogenMod. I'm looking for one that does it gradually based on the time of day.

no answers for a while someone found out something new?

From the official website:

"When is the Android verson coming out?
We have a version internally (it looks beautiful!) but it requires a very complicated installation process. We are working to simplify this and ship f.lux to the Android OS as soon as possible."
