GoodNight

There's a similar, more flexible, open source app you can sideload via Xcode here: https://github.com/anthonya1999/GoodNight . I use it on my non-jailbroken iPhone and iPad. Does the trick for me (all orange, all the time).

If they'd open source it, users would be able to compile for their own devices just fine. There are fully open alternatives that Apple doesn't mind, like https://github.com/anthonya1999/GoodNight I know where they're coming from, but all this wolf crying is getting annoying. I wouldn't mind if they came clear and said "we can't open source f.lux because we want to pressure Apple into letting us monetize it someday."

Has anyone tried GoodNight [1] on iOS? > Based off of Thomas Finch's "GammaThingy" > GoodNight is an app that allows you to directly access the screen's gamma levels, and modify it using IOMobileFramebuffer. With this you can do any of the following: Change the screen temperature, Put the brightness lower than iOS would normally allow you to, Adjust the RGB values of the framebuffer > This application uses dlsym, which loads in the private symbols at runtime, rather than using headers, so no additional setup is needed once you download the source.
