About

Chord Invaders

Features
Read full description

Chord Invaders is a chord-detection game for acoustic and electric guitar. Chord names fall from the top of the screen β€” play the chord on your real guitar before it reaches the bottom and watch it explode. The app listens through your iPhone's microphone and recognizes what you play in real time. Hit chords earn points. Missed chords cost lives. SEVEN LEVELS, ORGANIZED BY KEY β€’ Level 1: G major (G, C, D) β€’ Level 2: G expanded (adds Em) β€’ Level 3: C major (introduces F) β€’ Level 4: D major (introduces Bm barre) β€’ Level 5: E major blues (A, E, B7, C#m) β€’ Level 6: Mixed minor keys (Am, Dm, E, F, G, C) β€’ Level 7: Color chords (7ths, sus chords, Cadd9) PER-CHORD FEEDBACK After each session, see your accuracy per chord, average reaction time, and a personalized recommendation telling you what to practice next. CHORD DIAGRAMS Every level shows the chord shapes β€” finger positions, frets, and barre lines β€” alongside a short note on the music theory behind why those chords are grouped. BUILT-IN TUNER A vertical-bar guitar tuner helps you get in tune before you play. PRIVACY No accounts, no logins, no analytics. Audio is processed entirely on your device and never recorded or transmitted.
