Practice ukulele chords one at a time — the app listens through your phone's
microphone and tells you if you played it right. Start simple, unlock harder chords as you go,
and work through a 210-chord library once you've got the basics down.

Debug build — chord-detection sensitivity is still being tuned.
1 Download the APK above on your Android phone.
2 Open it. Android will warn about installing from an unknown source — tap
Settings and allow it for this file, or your browser.
3 Open the app and grant microphone access when asked — that's how it
checks your playing.
🎸
Listens as you play
Strums a chord into the mic, matches it against what's expected, and tells you pass or retry.
🌟
Tiered difficulty
Starts with one-finger shapes like C and Am, and unlocks harder chords as you master each tier.
📚
210-chord library
Every major, minor, seventh, and extended chord across all 12 roots, generated from real music theory.
🎵
Play-along songs
A handful of traditional, public-domain songs with chord charts to strum along with.
This is an early build, shared directly rather than through the Play Store —
expect rough edges. Chord detection has been tested against synthetic signals but not yet extensively
against a real mic and instrument, so accuracy may need a sensitivity adjustment in Settings.
