Learn ukulele chords the easy way.
Ukulele Chord Helper is a clean, offline-first reference app for the 4-string GCEA ukulele. Browse, play, and quiz yourself on 108 chords — with full diagrams, fingerings, and real synthesized chord sounds, no internet needed.
[Chord Library (108 chords — every sharp and flat)]
All twelve chromatic roots, none missing:
C · C# · D · D# · E · F · F# · G · G# · A · Bb · B
- 12 major · 12 minor
- 12 dominant 7th · 12 major 7th · 12 minor 7th
- 24 suspended (sus2 · sus4)
- 12 diminished 7th · 12 augmented
Chords with two spellings — C#/Db, D#/Eb, F#/Gb, G#/Ab, A#/Bb — are found by searching either one, and both names are shown on the chord.
Each chord shows clear fret positions, finger numbers, barre indicators, and plays a realistic ukulele sound on tap.

Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
• The chord dictionary now holds 108 chords — every one of the 12 roots, sharps and flats included, carries the same set of qualities.
• Category chips are localized, and the quiz shows both spellings of a root (C# / Db).
• Fixed a crash on iPad that came from the ad slot.
