Ratings and reviews

Nice app but the pixel filter causes unusable pink screen on lower brightness, and otherwise on lower brightness colors are innacurate. It would be nice to have a color calibration tool for lower brightnesses. This isn't the developers fault though, it's Samsung's. Oh, also it would be honestly AMAZING if the app had widgets to add to home screen, so I can control brightness from there. Preferably 4x1 and 5x1 widgets with brightness sliders.

It works, eye strain noticeably reduced, no ads, the only issue is full device access by which app has constant access to everything that is shown on the screen. Not really sure if it's possible to send that information to the remote server anyhow.. but yeah this is how it has to be to use this overlay, shame google does not provide such features as an integrated component of the Android system.

Using on Pixel 8 and it does truly eliminate PWM flicker. That said, it's a software solution to a hardware issue, so it's not perfect. These are the biggest problems for me: 1. Colors are extremely washed out in "Natural" color mode, so you have to switch to "Dynamic". Probably a system limitation. 2. Quick Setting tile doesn't accurately change status to reflect current state. 3. Uses unnecessary "INTERNET" permission which is concerning for a simple offline app with accessibility permission.
