Not Bad

The app it’s self is great! I like how it looks, I love the idea and for practice it really is great! However, I just wish they had better songs. Now I know this app is new. When I heard about it a year ago it wasn’t even on the App Store so I know it is really new! I just wish they had songs that I really could sing to. New songs. Scales would also be really great. As a music student, scales would really wish they had scales. Because this app is great for choral students, but there aren’t enough song options yet. I hope thy add some more soon!

Fantastic tool for learning music/harmony!

Can’t say enough good things about this technology. This app can scan your music and help you learn it perfectly for an up-coming audition! I’m a professional musical theatre actress and this really helps me in a pinch when I have to learn a new song fast. Really replaces the need for a voice teacher to plunk our your part. Scan your music either with a picture or upload a PDF and bam you have your part ready to learn in minutes. It’s a brilliant tool and I will be using it for all my music and harmony learning needs for years and years to come! Highly recommend.

Almost Great

I’m not sure about others, but I’ve had issues with not all the notes on music I import (either via camera or uploaded file) being correct. 90 plus percent is great, but wrong notes are jarring and don’t help with practice. If we had an interface for being able to review and correct the translated notes, this app would be phenomenal. But for now I still find myself going back to a piano to plunk out my line so that all the notes can be correct.

I’ll be thrilled to see this functionality in an update, or to be informed it’s an option I’ve somehow overlooked. Getting my music to 100% correct so I can practice it all would be worth five stars, a renewed subscription, and more!

Developer Response ,

Hi! Thank you for your feedback and review! Your suggestion about having more control over the song editing/importing functionality is a feature that we have on our radar. If you'd like to vote for that on our productboard, it will help us prioritize which features our users consider the most useful. If you haven't already done so, please shoot us an email at so that we can take a look at the issue that you've been having with your music not being imported correctly and continue this conversation. :)
