Better World Studio have released HarmonyAngel, available as a FREE download with optional in-app purchases for various subscriptions and a lifetime licence.
Turn one MIDI note into chord-aware harmony, control pages and progressions, and use the built-in synth or AUv3 MIDI processor in your iOS music setup.
HarmonyAngel is a MIDI and vocal harmony processor for musicians who want one monophonic line to follow the active chord.
Choose chord slots on two performance pages, then play from a MIDI controller or the on-screen piano. For every incoming note, HarmonyAngel can generate descending chord tones below it, align voicings to a chord root, preserve slash-chord roots, and forward aftertouch to the generated harmony.
Turn on Mic Input to sing into HarmonyAngel. The app performs low-latency monophonic pitch detection locally, uses the detected note to create chord-aware MIDI harmony, and provides a live tuner and input- level meter. Premium users can optionally hear pitch- corrected lead vocal and pitch-shifted vocal harmony audio, with selectable pitch detector, pitch shifter, formant, latency, buffer, trigger-level, and trigger- velocity controls.
Use HarmonvAngel standalone with CoreMIDI and the built-in sine synth, or load the AUv3 MIDI processor inside a compatible host. Page controls, progression stepping, hold behavior, custom chord types, selectable MIDI ports, channel routing, keyboard range, display transpose, and velocity shaping are available from the performance UI.
HarmonyAngel is designed for keyboardists, singers composers, producers, worship musicians, live performers, and anyone who wants fast chord-aware harmony from simple MIDI or vocal input.

- Two pages of 12 editable chord slots with no-harmony slots
