Ratings and reviews

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.

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.

this is the best app, it helps me find keys when am in a situation of not being sure or able to utilise the key, once I go on to the app... hmm.. am being helped though its not a app that's everywhere, I tried to search for it on other phones like Huawei and Intel, pshhhh it was no where to be found and that's the only problem am mostly having with the app though its a good application
