Mr Fred Z ,


You could not have a better practice app! As a teacher this is one of the most important and valuable apps I’ve ever seen, let alone use! Parents are foolish to pass this by, your child will soar! As just a player, I am challenged all the time ! It doesn’t matter if I am playing my Flute, Saxophone, Clarinet, Viola, Cello, or Violin ! There’s a huge selection of music and skill levels for me available! I’m actually thinking about learning the piano, the easy layout, note by note play, along with the assessment tool, it is an attainable goal! Now if I can just find the time or maybe French Horn! Thanks for the teacher support and a fantastic product!

Hello, Mr Fred

Thank you very much for your support!!
Violy App is in fact free to use for every verified music teacher.
You can verified your music teacher identity by following the instructions on "Me" - "I'm a teacher" page.

Violy App is just a tool, we provide tech services in order to reinforce the connection between music students and teachers, instead of music self learning. We know that it is very difficult to master classical music instruments without the help from professional instructors.

Well, we just help music teachers, and will keep improving the App :)
Please feel free to contact us at
Have a HAPPY practice!

Constantly improving

I’m pretty sure I wrote a review before. But I must say the app keeps improving. I just discovered that they added piano accompaniment which is just awesome. I don’t know if it’s available for free trial because I signed up for paid subscription. I truly love this app. I love the fact that you can change metronome to any speed And the fact that you can practice in small chunks. Please add wohlfahrt études.

Great App

This is a great must have app that helps you playing your Violin. I have tried a couple of different apps and none of them actually had the options this app gives you. There were just one recommendation about a delay start, and they responded quickly and are looking into it in the next update.

Developer Response ,

Thank you very much for the review!

We will release the new version soon which will support the feature you requested.

Hopefully you can expand this app to your friends, and help to let more people know the app.
