Chordlux

About

Chordlux helps beginner guitarists do the two things that matter most: learn the chords, and get fast at changing between them. • Chord library with clear diagrams and sound — open shapes, 7ths, sus, add9 and power chords, plus barre and advanced shapes with Pro • One Minute Changes drill — switch between two shapes for 60 seconds and tap once for every clean change. No microphone needed, so it works in a noisy room and never judges you wrongly. • Smart practice that picks the changes you're slowest at and brings them back until they're fluent • Progress for every pair you practise, plus a daily practice streak • Tools: metronome with tap tempo, key helper, circle of fifths, capo calculator and strumming trainer • Left-handed diagrams, light and dark themes • Works offline. No account, no login, no subscription. Chordlux is free with ads. A one-time Pro purchase unlocks 11 barre and advanced shapes (F, B, Bm, maj7, m7, dim, aug) and 5 more strumming patterns, and removes ads. Or remove just the ads with a separate one-time purchase.
