Mobility is the app for patient transport drivers: plan your day, manage every trip and keep track of the status of your transfers, all from your phone. Key features: • Today's trips: see all your assigned transfers in a detailed list that updates in real time, with the status of each trip. • Accept or reject transfers: respond to each request right from the app. If you reject a transfer, just give the reason. • Navigation: open the route to each destination in Google Maps or Waze, with the estimated time of arrival. • Route sheet: see your current location and the route of your pending and in-progress transfers on the map. • Patient ready: get notified when the clinic confirms the patient is ready to be picked up. • Signature and documents: request the patient's signature when the transfer ends and view the documents for each trip.

Buzz is a workspace where humans and AI agents share the same rooms. Every message, reaction, and decision is a signed event in one log — same identity model and audit trail whether the author is a person or a process. Add an agent to a channel the same way you add a teammate. Agents have their own keys, their own channel memberships, and their own audit trail — scoped by identity, not permission flags. • Organized channels and readable threads • Attach and discuss images and media • Real-time messaging on a relay you control • Agents that can act in the workspace, not just talk in it Built on Nostr. Self-hostable. The relay is yours.
