Ratings and reviews

All I was expecting out of this download was to make learning my scales a little easier. For me, this proved to be so much more than that. Within just an hour of trying it out, I'm playing along to all my favorite bands with so much more accuracy than before. It sincerely blows my mind that this is a free app.

Gets the key accurately within a few seconds. Tested it by playing music which I knew key of, from my DAW, and it was correct every time. Useful because downloaded MIDI tracks and sheet music are sometimes not in the key the song is actually performed in. Once you know the real key it's easy to transpose. Transferring the result to Antatres Auto-Tune in the DAW requires logging in to your Antatres account. It's easier just to set Auto-Tune manually once you know the key. It could be improved if it had tempo detection. So it could also tell you the bpm of the song it's listening to.

This is a very good app. I thought it was unreliable at first, but the trick is to have your music up very loud with your phone right by the speaker. Another good thing to add would be the option to have the key displayed in Camelot key. For example 6A(G minor) 7A(D minor) and so on.
