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!
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

I've used this on several phones but it has a nasty habit of completely locking the screen due to a bug.
When it works, it's probably a useful app, but I've had too many issues with it.

You can hit pause to overcome the overlay issues from the pull down notification area, the overlay issues were driving me nuts until I noticed that pausing the app fixed the permission problems.

Same here. Every time something strange happened with my phone, whether I couldn't click to install an app or change a setting with something else, it was because of this app. I agree that it does what it says it's going to do (in terms of changing the screen, I can't comment on whether this improved my health/sleep), but it isn't seamless enough to not be annoying for me. I kept it on my old phone for a year or so but after getting a new phone and reviewing which apps to install, I didn't install it again.

Android 7 has a blue light filter option built into it (for those who have or can upgrade to it)

This looks awesome. How would it compare to say F.lux? My OnePlus has a Night Mode but you can't schedule it.

If you're rooted, you can use Tasker on your OnePlus and have night mode activated on a timer. If you prefer the red hue added by Twilight to the yellow hue from Night Mode's reduced blue light, then this is perfect.

This randomly stopped some apps working last time I tried it, luckily now it appears to be a built in feature in Nougat (at least, it is present on my HTC 10)
