"Twilight" is an app that filters blue light from electronic screens, reducing eye strain and improving sleep quality. Blue light, particularly in the 460-480nm range, can suppress the production of melatonin, a hormone that regulates healthy sleep cycles. "Twilight" adapts the screen's color intensity to the time of day and local sunset and sunrise times. The filter intensity is smoothly adjusted to protect the eyes with a soft and pleasant red filter, making it easier for people to fall asleep. The app also has other benefits, such as making night reading easier and prolonging AMOLED screen life. Additionally, it is compatible with Wear OS devices. The app requires permission to access location, running apps, write settings, and network, and may request enabling the Accessibility Service to filter notifications and lock screen. Finally, the app references scientific studies demonstrating the impact of light exposure on sleep quality and circadian rhythm.
