These days you don't even necessarily need a separate app like F.Lux or Redshift; Windows and Android have similar color-shifting features built-in to the OS. (Not sure about Mac or iOS.)

IDK about iOS, but Android's built-in night mode barely changes anything. Try Twilight.

If you have rooted, try f.lux on Android too. Personally, I can't stand Twilight's "orange tint over content".

There are also other night mode apps that offer other tones. I've been using Blue Light Filter on Android lately and appreciate the level of controls it offers (color temperature, intensity, and screen dim)

It's not a matter of choice of colour, the way f.lux removes the blue is different than just adding an overlay (like Twilight and such do), that's why it needs root.

It's adjustable. At the highest setting it is unbearably yellow.

By default, the night mode on my Samsung indeed barely changed anything. But it does have a slider, so I was able to make it much redder.

It might depend on the brand. On my Nokia, the default is yellow enough to be fairly noticeable.

The Android P developer preview has an automatic Night Light feature that works really well.

iOS does but is very subtle about the change. f.lux default settings are quite dramatic and turn the screen very red. Something in between seems right to me.

One day the weather app will get the outside colour temperature locally and match the OS to it. :)

Does anyone know of any way you can keep Night Shift on at all times on iOS or MacOS? It seems when I turn on Night Shift, it automatically turns off next morning when it's daylight time.

I think the same things applies to f.lux on MacOS. I would like for it to be at 1200K at all times but I guess that's not doable and it grinds my ears a bit because you can't do so.

Try setting a custom schedule from 12:00 AM to 11:59 PM.

The change on my iPhone (on max temperature) is very noticeable.

ios does, not sure how good it is though

It's called Night Shift on MacOS.
