Overview of Twilight Pro APK for Android

This app makes your device screen adapt to the time of the day. It filters the flux of blue light emitted by your phone or tablet after sunset and protects your eyes with a soft and pleasant red filter. The filter intensity is smoothly adjusted to the sun cycle based on your local sunset and sunrise times.

Recent research suggests that exposure to blue light before sleep may distort your natural (circadian) rhythm and cause an inability to fall asleep. The cause is the photoreceptor in your eyes, called Melanopsin. This receptor is sensitive to a narrow band of blue light in the 460-480nm range, which may suppress Melatonin production - a hormone responsible for your healthy sleep-wake cycles.
