Ratings and reviews

would like to give 3.5. it doesn't always automatically start, which on one hand is fine, but the autostart helps me police my phone usage before sleep. the settings are thorough, from my limited knowledge of bluelight filters. it doesn't always run in the background even though that permission is granted.

I paid for the premium version, and I am a bit disappointed. Despite setting response slow it often flickers. You need to introduce some threshold and/or use average value over certain time so that the app would not react on slight environmental brightness changes. When it is dark, it seems to react to its own brightness changes when the device detects its own light reflecting on my face.

s24fe was unusable to me despite using comfort shield on and having display set to natural. jt always hurt my eyes. After using this and setting it to 16% I'm able to use my phone now. I'm just wary if if could see ny data and inputted passwords. taking a screenshot with this filter also changes the photo. it makes them appear much more orange and faded. and I think it influenced the photos I took as they appear much darker in the gallery. so this app is not perfect but it makes s24 usable
