Wish it would stay on at all times. Have to keep turning it back on.
Great app for filtering blue light. Be aware though: if you have an Android phone and an app is asking you to turn screen overlay off to access permissions, open THIS app and turn it off. Then go back to the app that was giving you the screen overlay error and continue what you were trying to do. Then you can return to this blue light app and click it on again.
This app works exactly as described. After using the blue block for a while, it was easy to see how glaring the phone is without this blue block app turned on.
I think this is a great app for eye security. And its brightness level is better. It contains minimum ads
Does exactly what it says for free and minimum ads
It's ok for evening viewing, takes the eye strane off.
