A great, wonderful, excellent app for voice training

My voice training session uses this app to help the patient to practice their feminine voice. As a patient I have to say this app is wonderful. Even though we have other options but this one helps me a lot and it's very easy to use. Just click on the icon and you can see your pitch, very fast, and the size is very small too. Finally this app has an update and it fixes bugs and makes the app better.
