Jebbio vs Chord Invaders

Jebbio — your reference for crafting solos, riffs, and melodies. Jebbio is a practical reference tool for guitarists who want to understand how chords and scales connect on the fretboard, and use that knowledge to create music. Built for guitar teachers, students, and self-taught players, Jebbio supports exploration and ear-based playing rather than step-by-step lessons or predefined licks. Choose the chord progression you’re playing or writing. Explore the keys and scales that fit your chords. See the notes on the fretboard, hear them, and explore freely at your own pace. Instead of running scales up and down, Jebbio helps you work with motifs, connect positions across the fretboard, and focus on phrasing, timing, and feel. Jebbio doesn’t tell you what to play. It gives you the tools to explore, understand, and create your own musical ideas.

Chord Invaders is a chord-detection game for acoustic and electric guitar. Chord names fall from the top of the screen — 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 • Level 1: G major (G, C, D) • Level 2: G expanded (adds Em) • Level 3: C major (introduces F) • Level 4: D major (introduces Bm barre) • Level 5: E major blues (A, E, B7, C#m) • Level 6: Mixed minor keys (Am, Dm, E, F, G, C) • 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 — finger positions, frets, and barre lines — 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.
