Ratings and reviews

First, the interface and instructions are horrible. I recorded and uploaded a song and then expected to see an option to see the transcription and there wasn't one anywhere. It turns out in the song book you click on your song and then the transcription is shown. Second, the transcription wasn't even close. I'm not Pavarotti, but I definitely can keep a solid key and the transcription was just all over the place. Don't waste your time like I did. And now they have my email address - ugh.

Liked the idea of it... But every song I tried to sing came out with flatted notes, and missing notes. I even had it listen to a song played on another music app, and it still butchered it. It also has no sense of depth in terms of song. It takes the loudest sound and puts half of it on the page, but ignores the bass that gives the piece feeling. It also can't tell when you're holding a note, and repeats the notes instead of extending the note value, or using a tie.

I uploaded a song that was written and sang by one of my students who wanted it transcribed into musical notation. It was in the key of A-flat major. The app transcribed it in G# minor. Not only were the notes wrong, and some notes missing, but it can't even tell what key it is in!? Worthless! I'm glad I didn't pay for this app!
