I'm one of those who isn't sure about f.lux and I've had it on my MacBook Pro for a couple of months now. Sure, I notice the color difference at night when it switches to Halogen, but my eyes don't feel the difference. I guess the default screen lighting doesn't bother me. When I used evasi0n, I thought I would install f.lux on my phone. Now I'm leaning towards deleting it off my MBP instead. It does what it says, just might not be for me.
Yea I hear exactly what you're saying. I don't need it on my computers. I could live without it. But it makes such a big difference on my iPhone. I probably feel this way because typically your iPhone is much closer to your eyes than a desktop/laptop computer would be and therefore, has a much bigger impact on relieving eye strain. Pus my iPhone is always much brighter than my computer. I guess I just love to take advantage of that retina display! Haha At least that's my experience. I guess it would all depend on how close you sit from your computer monitor and how close you hold your phone to your face when using it plus what you typically use for a brightness setting.
