From the developer:
jamTutor is the mobile teaching app for use with jamstik "The Smart Guitar". Together, these make up the only system that displays a player's fingers on screen to present right from wrong while learning to play. The app provides one-on-one feedback as you're presented with interactive activities such as video lessons, arcade challenges, and open play practice to master chords and scales.
