Violin player
I have been using the apps for about two months for my violin practice . It’s very useful to train up your tempo with new music pieces and make practicing less boring with piano or orchestra accompaniment. The library is gigantic with almost all the songs I wanted to learn. I have used other apps in the past like Metronaut but their library is more limited . The flip side is for most of pieces they don’t offfer finger annotation. Even for some etudes which you normally come with fingerings like Mazas and secvik etude .
