For families, crews and teams

Know where your people are. Even when the phones stop working.

Everyone in your group shows up as a dot on one private map, with group chat and an SOS button. If the cell towers go down, small radio tags keep the dots moving. We set it all up, run it on our own servers and teach your people to use it.

A real screenshot of our map over Los Angeles: live aircraft and freeway incidents. Your group's people show up the same way.
See it happen

Someone wanders off. Your phone tells you.

  1. Grandpa wanders off. He has a tag the size of a matchbox in his pocket. No phone needed.
  2. His dot moves on your map. You watch him head out the gate, live.
  3. Your phone buzzes the moment he's outside the park, with the spot on the map.

A drawing of what you'll see. You draw the fence on the map with your finger; the alert is built into the free map app, and we set it up with you.

The real thing, on our own map (24 seconds, sped up 2×): a fence around the Rose Bowl and test tags for the family. Dad’s phone keeps a line on Grandpa, and when Grandpa walks out it shows Geo Fence Exited.

How it works

Three things, that's all

  1. Carry a phone or a tag

    Your people install one free map app on the phone they already own, Android or iPhone. Anyone without a phone, or going where there's no signal, clips on a tag the size of a matchbox.

  2. Everyone's on one private map

    Only your group sees your group. On the same map: chat, who's where, planes overhead, fires, earthquakes and traffic, each one on or off with a tap.

  3. The right phone buzzes

    Someone presses SOS, a fire starts nearby, a tag goes quiet: the people who need to know get an alert with the spot on the map. And when you have a question, a person answers, not a bot.

Picture it. Your family is spread out at a packed stadium and the phones show full bars but nothing sends. Her tag and yours talk to each other by radio, so your map still shows her by Gate C, two sections over. You walk straight to her.

What you get

Working today, not a slide deck

Every card below runs on our own servers right now. The label tells you honestly how far along each one is.

Your own private map

running

Your group on its own map, on our own servers, not a big tech company's. Every phone gets its own digital key, and everything it sends is encrypted.

Radio tags, no signal needed

running

Small waterproof tags talk to each other by radio, so a person shows up on the map with no cell service and no phone.

An assistant in your chat

running

Ask it in plain words: "where's Dad?", "circle the campsite", "route me back to the truck". It answers and draws it on the map.

What's happening around you

running

Live aircraft from our own receiver, wildfires, earthquakes, freeway incidents and traffic cameras, on the same map as your people.

Taught by a person

running

We set up each phone with you and teach one tool at a time, outdoors, with a short drill. There's a free course to start on your own.

Sensing that sees through smoke

in the lab

Car-grade millimeter-wave radar for people on the move and in the dark. No cameras. What we're building.

Sensors, built to order

case by case

Gates, fences, water levels, weather, equipment that should stay put. If it can report, we can put it on your map. Examples.

Who it's for

Anyone who needs to find their people

The same system the military, firefighters and search teams use, set up and sized for you.

More examples
  • Families. Kids, grandparents, the dog. At home, on the road, at a crowded event, or when a storm takes the towers down.
  • Ski patrol and lifeguards. Every patroller and guard on one map, towers and boats included.
  • Remote work sites and camps. Crews and vehicles where there's no cell coverage at all.
  • Search, response and volunteer teams. One map, one chat, everyone accounted for.
  • Businesses and facilities. Your people, your equipment and your alarms in one place.
Words you'll hear

The jargon, in plain English

You don't need any of these to get started. But you'll hear them, so here's what they mean.

TAK
The map-and-chat app used by the U.S. military, firefighters and police. Free. We run the private server it connects to.
ATAK / iTAK
The Android and iPhone versions of that app.
Mesh
Radios that pass messages hand to hand, tag to tag, with no cell tower in between.
Tag
A small battery radio you clip on a person, a pack or a pet. It puts them on the map.
Server
Our own computer that keeps your group's map private. It's on our bench, not in a rented cloud.
Who builds it

Built by an electrician who wired war zones

Andrew Bowen spent his career building power and communications where failure wasn't an option: military bases in Afghanistan and Iraq, U.S. embassies on four continents, microwave towers and fiber backbones. He builds this the same way: documented, tested, and boring on purpose.

Master electrician (retired) · FCC licensed radio operator KJ6YJR · FAA licensed drone pilot

Next up is sensing that works in the dark and through smoke, and camera-free fall detection for elder care. What we're building.

Getting started takes one email

Tell me who you are, how many people, and what phones they use. I'll set up your private group, get every phone on the map with you, and run your first training session. See plans.
