[2012-06-22] Jeffry: Annoyed me simple and straight forward, but the fact that it went back to mac volume every time was enough for me to uninstall and use another app. |

[2012-06-04] pkr8ch: Very nice! This frequency generator works well, and seems to be bug free, only thing that would make it better is the ability to generate multiple frequencies simultaneously. |

[2012-01-06] Cody Wilson: Simple and Sweet: Does what it says and does it well. The developer also listens to feedback. I am suprised at how often this app has come in handy. |
