Never run out of chords to practice.
ChordDeck generates randomised chord progressions across genres and difficulty levels — with built-in chord shapes, scales, and a metronome — so you build real muscle memory instead of looping the same four chords.
Practice tools built for real progress
One app for randomised practice sessions, a full chord-shape library, scale shapes, and the metronome to keep it all in time.
Practice Generator
Generate fresh chord progressions by genre — Pop, Rock, Indie, Folk, Blues, Funk, Punk — and difficulty, from open chords to barre and power chords, so every session feels new.
Chord Shapes
Browse major, minor, 7th, m7, maj7, sus2, sus4 and diminished shapes on a clean interactive fretboard, in every key.
Scales
Learn major and minor pentatonic scale shapes, chord tones, and triad positions across the whole neck, with a slide animation between keys.
Built-in Metronome
Keep tempo with a metronome and practice timer built right into every session — no second app required.
Diagram or Numbers
Switch between visual chord diagrams and classic fret-number notation, whichever you read faster.
Save Favourites
Bookmark progressions you love and jump straight back into them next session, across all your devices.
