A free tool that adjusts your wallpaper on a timer

SunsetScreen is a simple tool that contains a series of sunrise and sunset wallpapers. It displays each on a timer so that your wallpaper appears to transitions from sunrise to sunset. For example, you may have the sun setting at 10pm and have it rise at 7am. The main reason for this app is to change your background colors over the course of a night, which is not great because you shouldn’t leave your computer on all night.

SunsetScreen allows you to warm the colours of the screen to avoid blue glare and sleep better at night

If you use a computer or laptop at night, you may notice how stark the screen is compared to the more ‘natural’ indoor lighting. SunsetScreen allows you to adjust the screen’s colour to the hue matched by your house’s light. An overly blue screen may also affect melatonin production in the brain which could prevent you from getting a restful sleep at night.

Compared to similar programs, SunsetScreen allows you precisely set the time of the sunrise and sunset. This is helpful in the winter months where daylight would only be limited to a few hours. In addition, SunsetScreen allows you precisely set the hue, saturation or brightness, a function not available in others programs of this type.
