Works great

This app is free, and works great, im sorry for the people who want to hurt their dogs ears and it doesnt work, but it works on humans just great, it also has a timer so you can hide your phone during class and do it in class so thats awesome too Im giving it a good review because its free and it does exactly what it says it would.
