The app does not automatically request camera access on Android 6.0. It displays a message saying " cannot access the camera" and freezes. You need to go to Android apps list and change permissions manually. When you finally get it to work, it works fine. A very limited number of masks available is huge flaw, especially that there is many paid ones available. I'd recommend to let users use more of these, otherwise vast majority will simply remove the app. Good luck to the creators!
