Ukulele Chord Library is a focused reference app for practice, arranging, and everyday playing. Browse chords by root and type, check clean fingering diagrams, review note content, and move through positions without digging through scattered charts or screenshots. The app currently includes 552 chord entries and 2,114 fingerings, covering common major, minor, seventh, suspended, and extended chord families. You can switch between open and higher-position shapes for the same chord and play chord audio to quickly confirm the sound you want. Mode Lookup helps you inspect the triads that belong to common modes, Chord Progressions gives you ready-to-use progression ideas, and Reverse Lookup lets you enter a four-string fret pattern and find matching chord names and playable positions in seconds. You can also save favorite chords, switch app language, and choose between block-chord or arpeggio playback. The app includes weekly, monthly, yearly, and lifetime PRO options, along with purchase and restore flows for unlocking a fuller learning experience.
