Really appreciate that I don't feel intense pain as I look at my screen. Edit: Would help if there could be an additional explanation about how "drawing over apps" refers to the filter going over everything and how we might have to turn it off to allow the play store or other apps to work. I know we turn on the permission first thing upon downloading this, but I misinterpreted the "drawing over" issue from the play store as a minimized screen like YouTube.

The app keeps turning itself back off every time my screen locks. I have the settings to allow it to use background data, and it still does it. I keep having to go back in and turn it on way too often. And sometimes it interferes with my other apps working properly. Please fix this or I will find a different app. My eyes are too sensitive to the blue light and it sometimes causes migraines and seizures, and I need the filter on all the time.

Better than other filters I've tried. It gives you options for how dark or light you want it. Fairly unobtrusive; does the job without a lot of annoying ads. Biggest problem is that I can't update other apps when it's running, and it's also caused some issues in games. But it's easy enough to turn it off and back on again.
