Scientific research has shown that melatonin - the chemical the brain makes late in the day - is reduced when exposed to blue light. By tempering this blue light, it becomes easier to wind down properly at night and, thus, have a more restful sleep.
Whether you're a morning lark or night owl, it allows you to set the time of the sunset and sunrise so that you can have full control over your sleep cycle.
Set the sunset time precisely.
Set the sunrise time too.
Choose by color temperature or by HSB for precise color.
Transition from one phase to the other gradually.
Automatically resides in the tray, so it keeps out of your way.
Loads automatically at Windows startup if you wish.
Instantly turn off SunsetScreen if you need to do color-sensitive work.
Choose from a range of presets, and reset to default if things go wonky.
Small, fast, elegant, and easy to use interface in less than a megabyte.
With this new version you can either upgrade after a week by paying $5 for the full version, or agree to the integrated peer sharing system to use Sunsetscreen for free (can be disabled at any time). If you accept, your use of SunsetScreen is free of charge in exchange for safely using some of your device's resources, and only when SunsetScreen is not running. You may turn this off from the Options window.
