Are you having trouble falling asleep? Are your kids hyperactive when playing with the tablet before bed time?
Are you using 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 and lockscreen 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 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 smart phone for a couple of hours before bed time 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.

PRO features
- more than 2 predefined profiles
- adjustable transition time
- option to turn off Twilight service altogether during inactive times
- new features will often first appear as PRO

Thank you very much for your intention to support our development. This is a pro application for the Twilight app. Please install on top, do not uninstall Twilight first.

    I'm having trouble sleeping and a friend told me to try blue light filter. I tried some free apps but there's little options and doesn't cover the entire screen. I rate it 5 stars for now. I will update if I encountered any problem. Hopefully it will also improve my sleep.

    This app is always one of the first I install on every phone. I read stuff on my phone to fall asleep, and if I didn't have this filter, I wouldn't get sleepy! Then I'd have to read books with a light on. UGH, no fun. This app has been the only light filter I need for many years now. My thanks to the devs!

    Love this app, but it needs some UI and Logic improvement. Firstly make it easier to select what apps the filter should auto disable on. Secondly, you need to add a way for it to automatically disable when taking screenshots, because the filter doesn't look as pleasent on a screenshot when shared to friends.

    I've been using this app for 2 years. Fully satisfied with it, thus switched to pro version. Provides almost every function in the free version too, but purchased the pro version since this app is incredibly helpful.

    I have been using Twilight for something like 8 years. Highly superior to inbuilt blue light filters. Definitely worth getting the pro version to support the developer.

    The blue light filter works for me for "dimming" the screen brightness; but Twilight give the ability to adjust the wonderful warm tones to give me what I need to fall asleep.

    Nice. But blocks some apps (like Google Play Store) while running.

    I prefer this app to the blue light filter on my phone.

    The best Blue Light Filtering Application ever.

    Better than the built in filter!
