What Open—Shape is
Open—Shape helps guitarists find playable chord voicings across the fretboard, including in different tunings. Its chord engine filters shapes by note count and shows difficulty and fingering details. Chords can be chained, reordered, played back, and saved as progressions. The Free plan costs nothing and includes the full chord engine, every voicing, 33 built-in tunings, real acoustic guitar playback, a microphone-based tuner, and up to three saved progressions. Pro costs $9.99, paid once, billed one-time, and adds unlimited custom tunings and saved progressions. The tuner identifies strings in alternate and custom tunings, and capo settings update voicings and progressions. A visual Canvas for connecting chords, tuning, and capo on a board runs in a desktop browser. The app is available on iOS and the web. No account is required; tunings and progressions are stored in browser local storage, and Settings offers backup export and import. The privacy policy says tuner audio is analyzed in the browser and is not recorded or transmitted.
