What ChordDeck is
ChordDeck is a guitar practice app for iOS and the web that creates randomized chord progressions. Users can choose Pop, Rock, Indie, Folk, Blues, Funk, or Punk, with difficulty ranging from open chords to barre and power chords. An interactive fretboard displays major, minor, 7th, m7, maj7, sus2, sus4, and diminished shapes in every key. Scale practice covers major and minor pentatonic shapes, chord tones, and triad positions across the neck. Sessions include a metronome and practice timer, with notation switchable between chord diagrams and fret numbers. Practice sessions and favourites sync between the two platforms. A free plan is available; ChordDeck Pro costs $2.99 a month and adds unlimited favourites, metronome speed control, advanced chord settings, and additional genres. The app may collect account, usage, and device information.
