Fun and useful
This is fun to play with. I'm not going to tune my piano or calibrate my audiometer with it, but it's useful to see what the main frequencies are in everyday sounds and noises. Its also a great conversation starter when you start whistling into your phone. Very cool app
Great for me
I just started using this app and I can see what the rave is all about. I am very happy with it, it is easy to use, simple design and easy setup.
