Who it is for
From loved ones to field teams.
Tools for families, volunteers and authorized teams, with different needs in mind.
01
Families
Message and call loved ones online; reach people nearby over Bluetooth during outages.
02
Volunteers
Keep short-range coordination alive in a neighborhood, camp, or field group: who is safe, who needs help, and where people are.
03
Teams and agencies
Authorized responder flows support role proof, dashboards, and controlled expansion modes for field coordination.
Know the limits
Resilient communication is not a rescue guarantee.
Connections depend on distance, surroundings, phones and battery power.
Range depends on the environment
Open air can reach farther; walls, rubble, crowds, and phone models can shorten the link significantly.
Preparation helps, but is not required
QR pairing can create a trusted contact locally during an outage. Testing beforehand simply makes an urgent situation easier.
It does not replace rescue services
SOS and location sharing can help nearby teams notice you; they do not replace emergency calls or local instructions.
The phone has to be on
Keep the phone powered on and Bluetooth enabled. In airplane mode, you may need to turn Bluetooth on separately.
When Infrastructure Fails
Three simple situations where Crisis Connect helps most.
Search & Rescue
