I still use f.lux because it has way more options and control than the built in Apple product. I wish I had it on my phone too, but I just suffer with Night Shift instead.

I've been very happy with Twilight on my Android device.

My Android (Pixel XL) has it built in as "Night Light" in the Display settings which I prefer.

I've used both Twilight and f.lux (rooted only) on Android in the past and Twilight's defaults are rough and needs too much fuss & attention to get the settings right. f.lux was buggy even tho I was rooted. "Night Light" is OK.

I've set iOS Night Shift to be active all day (start at 8:00 AM, end at 7:59 AM, something like that), can't look at the phone without it now.

Sorry, what exactly is causing you to "suffer"? It's an option to warm up the color temperature on your screen.

The lack of programmability, like I have with f.lux.

I can only make it come on and off at a certain time, and the color temp is just a slider with no numbers.

With f.lux, I can have day, evening, and night, and it adjusts automatically to my location. When I travel, I have to adjust the time on my phone.

All little things, but it shows how f.lux is polished and Night Shift is not.

Um, your time updates as you cross time zones on a cellular phone. Why would you have to change Nightshift? 20:00 is 20:00 no matter where you are.

Because time zones span ~15 degrees of longitude, and the sunset can be up to one hour difference between each side of the time zone. Also, I move north and south during my travels, which also changes sunset, and is not reflected in the time zone.

Those are some very specific requirements then, you are indeed suffering, I hope you find peace.

My main gripe is that it only has a single color temp setting. I use three with f.lux and it makes a huge difference. 5800K during the day, 3400K in the evening (between sunset and 11pm) and 1900K after 11pm, until an hour after sunrise.

My phone is jarring in the evening because it's way cooler than my display.

Night Shift's warmest setting is nowhere near as warm as f.lux's. I, too, miss it dearly on my iOS devices.

How much warmer do you want? The screen is basically burnt orange at this point.

I want candlelight. I replaced a bunch of bulbs in my house so that before I go to bed I have no light sources warmer than a candle, other than my phone.

If you're jailbroken you can use f.lux on iOS. I've been using it for years.
