KOviolin ,

Incredible, great work!

A music app I am actually willing to pay for...
I have struggled most my life with practice. I’ve had a lot of pressure put on me as a “golden child” when I showed natural ability from a young age. After awhile I didn’t know if I was playing for me or for my parents. This artist’s block has lasted me since age 16. On my fifth or sixth attempt, at the beginning stage of this #100DaysofPractice I downloaded this app after seeing an ad on IG. You guys have legitimately changed my life. I actually look forward to practicing instead of dreading. I have recommended this app to most of my students. I cannot thank you enough. You’ve made practicing Classical as fun for me as Jazz. You’ve accomplished something no one could do in my classical playing life. My future wins audition self will thank you, I thank you.
***what would be helpful is adding more concerti for violin, the real ones for professionals like Mendelssohn, Brahmns, Tvhaikovsky, Sibelius, etc. More advanced pieces would help you compete with Cadenza and Nomad.

Developer Response ,

Finally a serious App for Musicians

This is not yet another sheet music App that tries to tap you away from paper with useless promises such teaching you how to play! This is a real App for amateurs practicing music who wish bring excellence to their daily practice. You play with orchestras and high quality back tracks that adapt to YOUR interpretation! Looping feature quite useful... High quality sheets and expanding repertoire.

+1 for the Watch App with amazing tuner that works independently from the iPhone.

I wish they propose options to import scores so we could stay focused in one place.

Great app

I love the concept, this app enables you to practice on your own along piano or orchestral accompaniments with plenty of features to help you. I play the violin and noticed new scores are added regularly which is great as it makes you discover new pieces to practice. The design also looks really nice compared to other accompaniment app ;-)

Well done
