Night Screen is an app (or website) that allows users to easily adjust the brightness and color of their device's display for a better nighttime viewing experience. It provides a blue-light filter that reduces eye strain and relaxes the user's eyes, as well as a dark theme for late-night browsing. In addition, the app (or website) also features a variety of themes, including dark, sepia, and nightshift, which can be customized to create the perfect nighttime viewing experience. Night Screen also includes a timer that lets users set a reminder for when to turn the night mode off, so they can go back to the regular display.
Discontinued The project seems to be no longer developed. The latest version, 0.2.4, released in August 2014, can still be downloaded from GitHub.
