Was great till recent Android update, but now doesn't work on pull down menu or wake screen and when u go from a nice filtered screen to jarring brightness, it negates all the benefits of having a blue light filter. Have to find another app till this is fixed, please developer, asking if you can fix this please? It uses to be the best app out there. Thanks

Ive used other blue light blocker apps and put up with BS. This one requires nothing of my phone...includes a choice of three colors...i like the black or soft grey...is free and NO ADS!! Its great at night in bed...no strain on eyes..esp sleepy tired eyes. I do recommend.

Works great. Only way i can use my phone when i have a migraine is with the yellow filter. Chose this app because it's the most simple, streamlined, and smallest app size I could find on the market. Love it!
