Ratings and reviews

the app is great, i just wish that instead of putting my phone at max brightness with no way to change that apart from the in-app darkening filter which destroys the colors without reducing the flickering, it would just let me apply the pixel filter.

The dimming overlay sometimes adjusts to landscape, but often it doesn’t. It stays locked to vertical resolution, leaving both sides of the screen exposed when rotated. To get it working, I’ve had to uninstall and reinstall the app multiple times—hoping it catches the orientation correctly. That’s not sustainable. It’s a great utility for Amoled screens where uneven brightness becomes distracting. When it works, it helps mask those issues effectively. 😔 But, Inconsistency Ruins That Advantage.

This app saved my life when I got a new Samsung Galaxy s23 and discovered I have PMW sensitivity. I've been using it ever since. Thank you so much for creating this. ♡
