Charlie Lesoine wrote in to let me know about his new app Accordo. This app is inspired by the highly collectible Suzuki Omnichord, offering a similar workflow in which you pick a root note and then "strum" through a selection of available chords. The app arrives bare-bones without MIDI or Audiobus, but he assures me that, "those and other features are planned for the near future in an update." Ordinarily I would be skeptical of a first-time developer, but these are the guys that brought us the arpeggio hardware device.
