What is the communication range?

In open air, 100m+ can be possible. Walls, rubble, and phone model can shorten that a lot.

Do I need to set up contacts before an emergency?

For private chats, yes. You add trusted people ahead of time with a QR scan. For SOS, no.

Yes. Messages are end-to-end encrypted on both paths: Bluetooth messages go directly device to device, and internet messages travel encrypted so the server cannot read their content.

How does it affect battery life?

In standby it is lighter. If you keep chatting, sending SOS, or using voice, battery use goes up.

Can I make voice calls?

Yes. With internet you can make voice and video calls. Without internet, you can still hold a voice call with someone nearby over Bluetooth; quality can drop if the link gets weak.

Do I need downloaded maps?

No. You can still share your location without a full map.

Does Crisis Connect use mesh networking?

Default civilian messaging uses direct Bluetooth links. Mesh modes are separate and controlled: secure responder mesh for authorized teams, and an opt-in nearby public coordination channel only when the user explicitly enables it.

Offline-First Communication

Any distance over the internet. Direct Bluetooth when networks fail.

Q: What does it offer while I have internet?

A full messaging app: end-to-end encrypted messages plus voice and video calls at any distance. When the internet drops, the same app keeps working nearby over Bluetooth.

Message your loved ones with end-to-end encryption and hold voice and video calls over the internet. When internet and towers go down, the same app keeps sending messages, voice notes, and location to nearby people.

For families, volunteers, and first responders

Not a dispatch service. Contact official emergency services first when available.

While you're online

A messaging app you'll use every day.

Crisis Connect isn't only for the moment of disaster. While you have internet, you message your loved ones with end-to-end encryption and hold voice and video calls at any distance. When the network goes down, the same app keeps working nearby over Bluetooth.

End-to-end encrypted messaging

Automatically find Crisis Connect users from your phone contacts; texts and voice notes arrive encrypted at any distance.

Voice and video calls

Clear one-to-one voice and video over the internet, adapting to your connection quality.

Voice notes, photos, and files

Not just text — your voice notes, photos, and files are end-to-end encrypted too.

SOS reaches teams online too

With internet, your help signal and location land on authorized response panels.

When the internet goes away, the app switches to the direct Bluetooth path; with your contacts set up, communication continues nearby.

Before a crisis

Set up the offline path before you need it.

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.

Who it is for

One local-radio foundation, three different jobs.

The site now separates the promise by audience: families, volunteers, and professional teams use the same app with different expectations.

Families

Add trusted people ahead of time; message and video call them at any distance while online, and reach people nearby over Bluetooth when networks are down.

Volunteers

Keep short-range coordination alive in a neighborhood, camp, or field group: who is safe, who needs help, and where people are.

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.

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.

Range depends on the environment

Open air can reach farther; walls, rubble, crowds, and phone models can shorten the link significantly.

Preparation matters

For private messaging, pairing trusted people before a crisis is the strongest path.

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

If a device is powered off or in airplane mode, it cannot send or receive. The link forms only between phones that are reachable.

When Infrastructure Fails

Three simple situations where Crisis Connect helps most.
