Are you exploitation your smart phone or tablet in the late evening? Twilight may be a solution for you!

WARNING: Android O does no allow the app to cover your notifications any more..

Recent research suggests that exposure to blue light before sleep may distort your natural (time unit) rhythm and cause inability to fall asleep.

The cause is the photoreceptor in your opinion, called Melanopsin. This receptor is sensitive to a narrow band of blue light in the 460-480nm range which may suppress endocrine production – a endocrine responsible for your healthy sleep-wake cycles.

In experimental scientific studies it has been shown an average person reading on a tablet or smart phone for a couple of hours before bed time may find their sleep delayed by about an hour.

1) Bed reading: Twilight is more pleasant on the opinion for night reading. Especially as it is able to lower the screen backlight far below the ability of the backligt controls on your screen

2) AMOLED screens: We have tested Twilight on an AMOLED screen for 2.5 years without any sign of depletion or over-burning. If properly designed Twilight causes less light emission (by facultative dimming) with more equal light distribution (dark areas of the screen so much as the status bar get tinted). This may in fact increase your AMOLED screen life time.
