About this app

Eyes feel tired during night reading on the phone?

That is due to blue light. Blue light from your phone and tablet screen is the visible light spectrum (380-550nm) for circadian regulation. According to the scientific studies, exposure to blue light imposes serious threats to retinal neurons and inhibits the secretion of melatonin, a hormone that influences circadian rhythms. It is proven that reducing blue light can greatly improve sleep.

Ratings and reviews

I have been using this app for years, and it is wonderful for dimming the screen at night. I find that I get really sleepy using my phone if the filter is set low enough, but I wake back up within minutes of turning it off. My only complaint is that on my new phone, it makes me turn on accessibility permissions nearly every single night before I can use it. The permission setting keeps turning itself back off between uses. The filter used to turn itself off sometimes on my old phone as well.

I wish it had a widget. The shortcuts that are supposed to turn it on or off don't work for turning it on. I have it set where if you hold volume up and power, it's supposed to turn it off and on, because the tiny little accessories man on the corner is way too easy to hit accidentally. Shake phone to turn off would also be nice.

Would of give. 5 stars if there was some kind of widget so I could it off and back on if I had too. Other than, excellent app! All the Android devices in my household have it installed. Works as it should and it's free! Best idea it was to install on the kids devices, no . Ore problems getting them to bed. It really does work, try it out people!!
