Love the app. Thanks for offering it to the public for free!

5/5 stars

Thanks a ton for writing this. It works beautifully and the interface is very well done. A larger on/off button might be nice.

4/5 stars
Very Handy Tool!

Quite useful for instrument tuning and for testing the frequency response of sound equipment. If an update ever materializes, I have only one request for the dev(s): please remove the dreaded pop that occurs when the tone starts and/or I change wave forms. That would make this app pretty much perfect.
