Twilight is described as 'The app filters the blue spectrum on your phone or tablet after sunset and protects your eyes with a red filter. The filter intensity is smoothly adjusted to the sun cycle based on your local sunset and sunrise times' and is a popular color temperature tool in the system & hardware category. There are more than 25 alternatives to Twilight for a variety of platforms, including Windows, Linux, Mac, Android and Wayland apps. The best Twilight alternative is f.lux, which is free. Other great apps like Twilight are Redshift, LightBulb, Solace and Red Moon.
Software that makes the color of your computer's display adapt to the time of day, warm at night and like sunlight during the day.
Great. Free. Lots of options.

Redshift adjusts the color temperature according to the position of the sun. A different color temperature is set during night and daytime.
Background application that adjusts screen gamma, making the colors appear warmer at night, reducing strain on your eyes.

The app is free on F-Droid and on GitHub but you can buy it on the Google Play Store to support the developer.
RedshiftGUI changes the color temperature of your monitor to better match that of your surrounding. This means that it sets a cooler color temperature during the daytime (due to natural lighting) and sets a warmer temperature at night (due to indoor lighting). Similar to f.

CareUEyes is a very simple but useful program when it is about your eye care. The program comes with a very simple and clean interface and needs to technical knowledge. Even a novice computer user can download and use it easily.
CF.lumen - don't let your phone blind you! CF.lumen changes the colors of your Android device's display based on the position of the sun. With the default settings, your display will get a warmer tint (lower color temperature) when the sun is down, to look more like indoo.
It seems technically better... it alters display gamma curve instead of just overlaying a semi-transparent filter like most of the others do.
Whether you're a morning lark or night owl, SunsetScreen allows you to set the time of the sunset and sunrise, so you can have full control over your sleep cycle.
You can set the exact time to dim screens, just like Twilight, and it not only adjusts colour but dims screen brightness, too. Two things that the leading competitor, Flux, doesn't do.
