Great for the office or classroom

This app was recommended to me by a family member and I recall downloading it with skepticism. After using this for 2 years, I have found it helps immensely with concentration and calming oneself in a world filled with increasingly hectic "open plan" offices. I would recommend purchasing noise canceling earphones for enhanced effectiveness. Wonderful app all around.
