Jamerator vs Chord Invaders

Open Jamerator, get a chord progression, press play, and start playing. If friends are around, everyone jams to the same chords on the same beat. RHYTHM Swipe for a fresh progression with the shapes to play it. Swipe back to any jam you've played. Set the tempo, move the key or add a capo, pick a count-in, and hear the guitar, the click, or both. LEAD The scales that fit your progression, lit up on a fretboard. Chord tones highlight as the chart plays so you always know where to land. TUNER A built-in tuner with a fine-tune meter. One tap away, no switching apps. JAM TOGETHER One phone starts a jam and nearby friends join over Bluetooth or Wi-Fi. No accounts, no internet. Everyone sees the same chords and starts on the same beat, and anyone can roll the next progression. Made for practice sessions, band rehearsals, and bonfires. Jamerator is free with ads, and a one-time purchase removes them forever.

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.
