Chordlux

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.
