Customer Reviews


This app is not only incredibly beautiful, it also works remarkably well! This is a masterful piece of development and I would love to see it kept up to date! I highly recommend this app!

Beats all I've tried

Why? Because of the way the colors change to reflect pitch accuracy! This means if I play a piece on my violin and the green flashes to red, I need serious pitch adjustment. Talk about instant feedback!

This is vital for any violinist, beginning or advanced. (I consider myself to be intermediate, fyi.)
