If internet and towers go down, you can still send messages, voice notes, and location updates to nearby people.
For families, volunteers, and first responders
Install Crisis Connect and add trusted people while things are calm. The setup is small, but it makes the offline path easier when networks are gone.
No account needed for core offline messaging
Install Crisis Connect and open the inbox once so the phone is ready before service disappears.
Scan QR codes with the people you actually need to reach: family, teammates, or nearby helpers.
Enable Bluetooth, nearby devices, and notifications so messages are not blocked later.
Try one short offline message together. You learn what works before it becomes urgent.
When internet and cellular service are down, your phone still works as a local communication tool.
Send secure text and voice messages directly to nearby devices even without internet or cellular signal.
Essential survival utilities including Metal Detector, Signal Finder, and Offline Maps in one integrated suite.
Access critical first aid, shelter building, and survival techniques stored locally on your device.
Trusted contacts and SOS chats, all in one place.
Thank god. Your dad is with me, we are at the park.
Stay calm. We are close.
ReadThe site now separates the promise by audience: families, volunteers, and professional teams use the same app with different expectations.
Add trusted people before an emergency; send nearby text and voice when internet and cell service are unavailable.
Keep short-range coordination alive in a neighborhood, camp, or field group: who is safe, who needs help, and where people are.
Authorized responder flows support role proof, dashboards, and controlled expansion modes for field coordination.
Emergency software earns trust by stating its boundaries. Crisis Connect adds a communication path when infrastructure is gone; phones, battery, environment, and nearby devices still decide the outcome.
Open air can reach farther; walls, rubble, crowds, and phone models can shorten the link significantly.
For private messaging, pairing trusted people before a crisis is the strongest path.
SOS and location sharing can help nearby teams notice you; they do not replace emergency calls or local instructions.
If a device is powered off or in airplane mode, it cannot send or receive. The link forms only between phones that are reachable.
Three simple situations where Crisis Connect helps most.
Plain answers to the basics.
In open air, 100m+ can be possible. Walls, rubble, and phone model can shorten that a lot.
Even without internet or signal, you can message trusted people nearby and send a help signal to rescue teams.
