Active and supportive developer

I found this app perfect for the kind of chord practice and retention training I wanted. Main perk is Zeal, the developer, is also very communicative and responsive with feedback and suggestions. I’m already in love with this app.

Super helpful for piano! Review

Really helps my piano chord practice

Great chord trainer for beginners

I'm currently learning piano, and this tool has been incredibly helpful for understanding and practicing chords. It makes the theory so much clearer. My only minor gripe is that the accompaniment patterns are a bit too basic. I’d love to see more complex styles in the future. Keep it up!
