Halo turns a spoken thought into a private note

Field notes

Halo describes a capture pipeline that begins with the iPhone Action Button and ends with several structured views of the same recording: transcript, summary, action items, and a mind map. Its page also shows routes through Apple Watch, Shortcuts, Back Tap, Siri, and audio import, while stating that processing uses one microphone permission and no network calls. The stated commercial model is ten free notes followed by a £14.99 one-time purchase, with no account or subscription.
