f. lux for iOS is designed to give you a better experience with your computer. It regulates the colors of your display so it can match the time of the day properly. That can reduce your eye strain or your headache or even help you sleep at night.

You can use sideloadly to install it and use F.Lux.

@Flux-Help said in Is there any way to set the display color filters on an iPad or iPhone to match the flux evening settings?:

Thanks. I've actually been doing something like that, but I can't seem to get the color to match the flux color I have on my laptop. On my laptop it's redish but I don't really notice it. When I set the hue to the pure red and adjust it's intensity, it's just different. It's goes from not red enough to suddenly too red and too dark. I'm wondering if anyone else has been able to actually match their iPhone/iPad display color to their laptop flux color?

I don't know but it doesn't have to be the same. It just has to be sufficiently lacking in blue light so as to not disrupt your circadian rhythm. Maybe try 800K on the laptop. That's very red, if not pure red. Or, try something not so red in the color filter in iPadOS.

This isn't a support forum for iOS. It's for f.lux.

Yes really there are two markets: eyewear manufacturers (including BluTech, from your link) have started filtering a little bit of light, but usually these wavelengths really don't make a big difference for computer screens. BluTech is unique because you can see the difference, so it does more than most.

Also, there are efforts to make screen covers, or to move the blue primary over a bit or to change screen spectrum by a tiny amount. There you find some self-described "standards" (no consensus standard) for blue-light safety in screens, with a ton of press about it. I like what they are doing for flicker, but the spectral changes cannot make much difference, and so the press around it seems very disingenuous:

Here are some examples:

https://fluxometer.com/rainbow/#!id=filter/BluTech - this one makes a visible change https://fluxometer.com/rainbow/#!id=filter/ZAGG Visionguard - this one claims to help your eyes without making a visible change

Based on the numbers, changing the brightness of your screen by any amount at all will make a bigger difference than this kind of filter.

I've tried changing several settings in Xcode, but the app loads and asks me to allow notifications then it just freezes :(.

You could uncheck "Start f.lux at login" and see if it works better then.
Still can run it by hand after.

Night shift does suck. F.Lux is the only reason I jailbroke.

I noticed that Apples NightShift gives me blurred text...

Really? I have no issues with night shift at all, have you tried night shift on any other phone in the apple store.
