ChordBloom turns music theory into a garden. Chords bloom as petals around the key you're in โ€” tap to hear them, wander to neighboring keys, and watch harmony make sense visually. EXPLORE HARMONY BY TOUCH Diatonic chords, the circle of fifths, relative and parallel keys, tritone substitutions, modal interchange โ€” each view lays the theory out as petals you can play. Long-press to cycle extensions (7ths, 9ths, 13ths), choose close, open, or spread voicings, and phrase chords as blocks, strums, or arpeggios. REAL SYNTHESIS, ON DEVICE A full SuperCollider synth engine runs right on your phone alongside classic synth voices โ€” warm pads, plucks, bells, keys, and ambient textures. Every note is synthesized live, and it all works completely offline. AI IMPROVISATION Let the built-in improviser play melodies over your chord changes while you drive the harmony. SAVE YOUR PROGRESSIONS Collect chords into palettes and build progressions you can come back to. MIDI OUTPUT โ€” OPTIONAL UNLOCK Turn ChordBloom into a chord controller for your whole studio: a one-time in-app purchase unlocks BLE MIDI to hardware synths and CoreMIDI to DAWs and other iOS music apps. No account. No ads. No data collected.

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 โ€” 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 โ€ข Level 1: G major (G, C, D) โ€ข Level 2: G expanded (adds Em) โ€ข Level 3: C major (introduces F) โ€ข Level 4: D major (introduces Bm barre) โ€ข Level 5: E major blues (A, E, B7, C#m) โ€ข Level 6: Mixed minor keys (Am, Dm, E, F, G, C) โ€ข 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 โ€” finger positions, frets, and barre lines โ€” 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.
