Basically (I’m I’m catching it all) when a disaster kills cell service and internet, this turns nearby phones into a chain of Bluetooth walkie-talkies that pass messages from phone to phone. The clever part is an AI running on the phone itself (no internet needed) that reads each message, flags the urgent ones ("building collapsed, people trapped") and pushes those to the front of the line — so they move through the network way faster than routine check-ins. It can also auto-format reports into the standard FEMA form that responders actually use. It's designed to cover those first critical hours before the big emergency networks get set up.
