Master 108 ukulele chords — every sharp and flat — with diagrams, fingering, and real-time synthesized sound. Three quiz modes. 100% offline.

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.

[Real Ukulele Sounds] Powered by a Karplus-Strong synthesis engine that simulates the four GCEA strings (with the reentrant high-G). Every chord plays in real time — no pre-recorded audio, no waiting.
