Your app has made my job as a teacher so much easier and my students love the app, too! The other day when we got back to the room without breaking the glass, the kids wanted to know if we could do an experiment. Since I let them purposely break the glass once we get back to the room , they wanted to start with a class wide whisper and gradually increase the volume to find out how loud they could be without breaking the glass. I have the sensitivity set to 70 which allows quiet talking. We increased our volume six times before it broke the glass. We are learning and having fun!
