SCROLL DOWN

Sometimes, they stop.
Storm, failure, outage — with no warning.

Where everything went dark

LASTLINE lights up.

No network, no server, no subscription needed. Everything your family needs already lives in the phone — and everyone can see the others are okay.

The Household · The Family Plan

Everyone knows what to do. Beforehand.

A simple plan, written together one Sunday evening. Who picks up whom, where you meet, what each person takes.

Offline · The Mesh

No network. No problem.

The family's phones talk directly to each other, device to device. Messages get through — even when nothing else does.

01
Everything lives in the phonePlans, guides, documents, maps: no connection needed, ever.
02
The family mesh*Bluetooth and Wi-Fi Direct relay your messages from one person to the next.
03
The scanner and the advisorThe on-device AI inventories your supplies and answers your questions — offline too.

* Off-grid mesh messaging requires a compatible mesh device. Its range and reliability depend on the mesh of devices around you — the more relays nearby, the better messages travel.

The Alerts · The SOS

When it matters, one second is enough.

Official alerts arrive before the panic does. And if one of you needs help, a single gesture warns the whole household — with their location.

01
Localized alertsWeather warnings, outages, official instructions — filtered for your area.
02
Family SOSLocation, battery level and a message sent to everyone close to you.
03
Distress signalMorse flashlight, siren, flashing screen: the phone becomes a beacon.

What it really is

Being ready is an act of love.

LASTLINE isn't a survival app. It's an hour spent together, one Sunday, so the worst day of the year is only a bad moment.

It should already be on every phone.

Free to start. Five minutes to build your household. Ready for good.
