Works as advertised with root. Actually eliminates blue instead of just adding red with an overlay. However, it really needs some simple QOL improvements. I find myself opening the app every morning to manually turn off the filter, and then later reenabling the filter, since it doesn't automation turn off at wake up time. There really need to be shortcuts, quick toggles, tasker integration, app activities, or similar for enabling/disabling bluelight and red only filters.

I have a rooted Nexus 5X running Android 8.1 Oreo. For a short while, this app seemed to work fine. However, after a few hours, I noticed that the app randomly causes the screen to lock up. Touches would be registered, but the display would freeze, forcing me to restart my phone. This has happened twice in two days.

Absolutely sublime stuff. I also use it on my computer as I am a writer/journalist with quite a lot of screen time. // But... For it to be used as an application, it does need root access for Android (not an issue on Windows pc), and that kind of sucks. So have not felt the same happiness I felt when I ised it on my pc. // Mandatory location seems to be unnecessary. Put an automatic timer in it, and you solve your problem.
