Our verdict on Open—Shape
Open—Shape is a browser-based and iOS chord and tuning tool for guitarists. It finds playable chord voicings across the fretboard in standard, alternate, and custom tunings, recalculates chords for capo changes, and supports chord progression building. Users can reorder and save progressions, play them back with recorded acoustic guitar sounds, and use a microphone-based tuner. Its focus is practical voicing practice rather than broad instrument support, making it a fit for guitarists who want to explore shapes and hear progressions in context.
The published plans keep the core experience accessible. Free includes the full chord engine, 33 built-in tunings, real acoustic playback, a microphone tuner, and up to three saved progressions. Pro costs $9.99 as a one-time purchase and includes everything in Free, plus unlimited custom tunings and unlimited saved progressions. That structure suits players who want to start with standard and built-in alternate tunings, while the upgrade is most relevant to users who regularly create custom tunings or maintain more than three progression ideas.
Open—Shape’s standout strength is the connection between playable fretboard voicings, tuning changes, capo recalculation, and progression playback. The desktop-browser Canvas workspace provides the main browser setting, while the iOS version extends access to mobile users. The product is a good choice for guitarists who value voicing exploration, acoustic playback, and a simple one-time upgrade. Players seeking support for instruments beyond guitar or a broader production environment should look for a more expansive alternative.
