What chord is that? Now you know. Play a chord, and SUS4 Chord ID names it. Hold a guitar chord up to the mic, play a few notes into the app's built-in keyboard, and the app returns the chord name and a set of common voicings on guitar and piano. It handles basic major and minor triads just as cleanly as it handles extended jazz chords and ambiguous slash chords. The history tab keeps a log of every chord you have identified, with optional notes so you can annotate as you go. Useful for writing sessions where you are building a progression and want a record of what you played, and useful for theory study when you want to understand what you are hearing. • Mic-based chord detection — play it in; the app names it • Built-in keyboard for manual input • Chord name display with common voicing diagrams • Supports simple triads through extended and altered jazz chords • Identification history with optional notes per entry • Subscribe monthly, or unlock the full SUS4 suite forever: unlimited identifications, voicing diagrams for common chords, and annotated history All audio analysis runs on your device. Your music stays private. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
