Lifeline.Get in touch

A connection, closer to home

When networks
go quiet,
stay within reach.

A way for nearby people to exchange requests for help and keep talking. From one phone to the next, over Bluetooth.

A different way to connect

One phone starts it.
The next connection carries it on.

Phones running Lifeline can form an Emergency Mesh: a local network that carries messages through encounters, rather than a mobile tower.

  1. 01

    Start with your phone.

    Set up Lifeline, allow the required permissions, and turn on Bluetooth. Core mesh communication does not need internet or cellular data.

  2. 02

    Reach a nearby connection.

    Create an SOS request or start a conversation. Messages are saved locally before the app attempts to pass them to participating devices.

  3. 03

    Let the next encounter help.

    A participating device may carry a message onward when another connection becomes possible. Receipts show what actually happened.

Nearby devices make the difference. Delivery is opportunistic, and a connection is never a promise of rescue.

Human, first

A clearer next step.
A little less alone.

Request assistance, keep a conversation going, or help carry a message onward. Different roles, all part of the connection.

Ask for help nearby

Say what you need.
Keep the request clear.

Create an SOS with the kind of help you need, its urgency, and the location you choose to share. Update, renew, or end it as your situation changes.

  • Rescue
  • Medical help
  • Supplies
01 / Keep talking

A conversation can
make a difference.

Exchange public or private chat through the same local mesh. Messages are saved before the app attempts to carry them onward.

02 / Carry it forward

Pass a message.
Choose your own role.

Your device may relay messages without making you responsible for responding. Offering help is a separate, explicit choice.

03 / Stay prepared

Useful guidance.
Close at hand.

Browse bundled preparedness guidance in English or Vietnamese. The app keeps official-call handoff separate from a mesh request.

Clarity when it matters

Know what happened.
Without the guesswork.

A message reaching a phone is different from a person offering help. Lifeline keeps those moments separate.

Explore the meanings below. This is an illustrative guide, not a live request.

Trying to Reach Devices

A request. Not yet a receipt.

The SOS is active, but no other device has returned evidence that it was reached. A local request alone does not mean somebody has seen it.

Example meanings only. No messages are sent.

Connection, with context

One more tool.
Keep your other plans.

Lifeline is a communication project, not an emergency service. It has no staffed dispatch team, guaranteed delivery time, or verified responder network.

Physical cross-platform validation and independent review are still pending. Use existing local emergency procedures and official services for a real incident. A test or an app status is not evidence that rescue will arrive.

Good questions

A little clarity
goes a long way.

What the mesh can do, what a receipt means, and where things stand.

Does Lifeline work without internet?

The core Emergency Mesh exchanges messages over Bluetooth without internet or cellular data. It still needs nearby participating Lifeline devices, Bluetooth, required permissions, and operating-system conditions that permit communication. Without those connections, a message may remain on your phone.

Does an SOS contact official emergency services?

No. Creating an SOS does not call an emergency number or notify a staffed dispatch service. A separately configured official-call control can hand off to your phone’s dialer when phone service is available. Use official emergency services and your local emergency plan for a real incident.

Is a device receipt the same as someone helping?

No. “Reached a Device” means another device returned receipt evidence. “Seen by a Responder” means someone viewed the request. “Help Accepted” means a responder explicitly committed to helping; it does not confirm that help has arrived.

Can messages keep moving while a phone is locked?

Background communication is best effort and depends on the operating system, permissions, Bluetooth, and battery controls. Force-quitting the iOS app or force-stopping it on Android ends operation until you relaunch. There is no guaranteed delivery time or always-on relay.

Who can see an SOS?

Current SOS content is signed but readable by relay devices after disclosure. Share only what is needed, especially when including location or medical details. Responder receipts are encrypted to the sender’s Device Identity. A Device Identity is pseudonymous; it does not verify a person’s real identity.

When can I download Lifeline?

Lifeline is in development for iOS and Android, with English and Vietnamese interfaces. Broad emergency launch is paused while physical-device validation and independent review remain incomplete. There is no public App Store download linked here. Contact us with questions about the project.
