ChordDeck

What ChordDeck is

ChordDeck is a guitar practice app that generates randomized chord progressions across genres and difficulty levels. Its generator covers Pop, Rock, Indie, Folk, Blues, Funk, and Punk, with progressions ranging from open chords to barre and power chords. Practice sessions include a built-in metronome and timer, and users can switch between visual chord diagrams and fret-number notation.

An interactive fretboard presents major, minor, 7th, m7, maj7, sus2, sus4, and diminished shapes in every key. For scale practice, the app covers major and minor pentatonic shapes, chord tones, and triad positions across the neck. Sessions and favourites sync between the iOS and web apps. ChordDeck has a free plan, while ChordDeck Pro costs $2.99 a month. Pro adds unlimited favourites, metronome speed control, advanced chord shapes and settings, and additional genres. The privacy policy says the app may collect account, usage, and device information, but not sensitive personal data. Apple handles subscription payments, and ChordDeck says it does not store or access full payment details. It may use third-party analytics or crash reporting to improve app performance, and says it does not sell or rent personal data.

Who it suits

ChordDeck suits guitarists who want randomized progression practice with chord diagrams, fret-number notation, a metronome, and a timer. Its synced iOS and web sessions can suit players who practise across both platforms.

Limits

The free plan is available. ChordDeck Pro costs $2.99 a month and adds unlimited favourites, metronome speed control, advanced chord shapes and settings, and additional genres.

Getting started

1. Visit chorddeck.app or use the iOS app.
2. Start with the free plan.
3. Choose a genre and difficulty for a progression session.
4. Use the fretboard, notation toggle, metronome, and timer while practising.
5. Choose ChordDeck Pro for unlimited favourites, metronome speed control, advanced settings, and additional genres.

Verdict

Choose ChordDeck for guitar practice built around randomized progressions, chord shapes, and neck-wide scale material. Look elsewhere if you need an instrument other than guitar, or if metronome speed control and unlimited favourites are essential without a paid plan.
