Are you having trouble falling asleep? Are your kids hyperactive when playing with the tablet before bedtime? Are you using your smartphone or tablet in the late evening? Twilight may be a solution for you!
WARNING: Android O does not allow the app to cover your notifications and lock screen anymore. We have some workarounds like wallpaper filtering etc..
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.
In experimental scientific studies, it has been shown an average person reading on a tablet or smartphone for a couple of hours before bedtime may find their sleep delayed by about an hour.
The Twilight app makes your device screen adapt to the time of the day. It filters the blue spectrum on 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.
