Both can explore it. Beginners can start with familiar open chords and short Theory Lab explanations. Players building their vocabulary can explore inversions, string sets and extended chords. It’s a dictionary and practice companion, not a full guitar course.
The current library has 45 chord qualities and 4,368 voicings for standard tuning, including movable shapes and familiar fixed-key grips. It’s a carefully bounded library, not every possible guitar fingering.
Custom chord creation is planned: place your notes on the fretboard and explore possible chord names. It is not available in the current app. Today, you can choose existing voicings, give saved chords your own labels and build personal collections.
Chord diagrams, synthesized playback and your collections live on your device. After purchase or restore, cached access works offline. When an online check detects an expired or revoked licence, you return to the paywall and keep your saved chords.
