Chord Foundry: Guitar+Ukulele

Find a chord shape you can actually use.

Chord Foundry is a focused guitar and ukulele chord reference with clear diagrams, audible previews, a microphone tuner, and a practical metronome. It keeps everyday chords approachable for beginners while giving experienced players room to explore.

SIMPLIFIED MODE: LESS SEARCHING, MORE PLAYING

For every major, minor, and dominant seventh chord across all 12 roots, Simplified mode presents a small, curated pair by default:

• one approachable non-barre fingering
• one movable shape with a strict full-width barre

No confusing pages of near-duplicates. No partial barre presented as an easy option. Conventional open shapes are prioritized, while alternatives are ranked for low position, compact reach, and practical fingering.

COMPLETE MODE: EXPLORE THE FRETBOARD

Need more than the essentials? Complete mode opens the broader locally generated catalog: 40 chord qualities for guitar and 26 for ukulele, across all 12 chromatic roots and the app's supported fret range. Explore major, minor, seventh, suspended, diminished, augmented, extended, added-tone, and other useful chord types in different positions and inversions.

EVERY SHAPE IS EASY TO READ

• Native guitar and ukulele chord diagrams
• Clearly marked open and muted strings
• Finger positions, fret range, and difficulty
• Honest full-barre detection
• Local audio preview for every displayed voicing
• Favorites for the shapes you want to keep
• Open, barre, beginner, maximum-fret, and fret-span filters
• Sort by easiest, lowest, highest, or open shapes first

TUNE WITHOUT LEAVING THE APP

Use live microphone pitch detection with automatic string recognition, or lock onto the string you are tuning. Choose from common guitar tunings including Standard, Drop D, DADGAD, open tunings, and lowered tunings. Ukulele presets include high G, low G, baritone, D, and Canadian tuning. Tuner audio is analysed on the device and is not saved or uploaded.

KEEP STEADY TIME

The built-in metronome offers:

• 30–240 BPM
• tap tempo
• 2/4, 3/4, 4/4, and 6/4 meters
• accented first beat and clear visual pulse
• optional vibration
