Whether you're a beginner who only knows 3 chords or an experienced worship leader, this app meets you where you are.

• Transpose — Move full progressions to any key instantly
• Ear Training — 3 levels, identify chords just by listening
• Play Along — See piano and guitar shapes in every key, with capo tips built in
• Circle of 4ths & 5ths — Tap any key to see all 7 chords
