Your own private map
runningYour 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.
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.
See it happen
Two real examples, filmed on our own map
No drawings, no mock-ups. These are the map app and our own servers doing it.
Someone wanders off. Your phone tells you.
- Draw a fence on the map with your finger: the park, the campsite, the stadium.
- Grandpa carries a tag the size of a matchbox. No phone needed.
- He walks out, your phone buzzes with who left and where, and a line on the map leads you to him.
The alert is built into the free map app. We set the fence up with you.
Phone · the alert
Watch · WearTAK
Find your car after the game
Thousands of cars, every row looks the same, and it's dark when you come out. Two short messages to the assistant do the job, and the pin shows up on your phone and your watch.
Park and send “mark my car”. Leaving? Send “go my car”. The phone says how far and which way; the watch shows the same pin and points at it: 1,564 ft. 
Tap the pin, then Bloodhound. A line leads you to the car on the phone, and on the watch, here in its new 3D view.
On your wrist: one double press
Double-press the watch's home button and our own mission app opens: one big button for the team, and the live freeway cameras nearest to you. The same camera plays on the phone's map at the same time.
Double-press home. The mission button, and under it the live cameras nearest to where you stand. 
Live, both at once. Caltrans camera 755 on the I-210, just after midnight, on the phone and the watch together.
The phone and watch shots come from our own test phone and watch, parked at the Rose Bowl, so they're marked simulated. The messages, answers, pins and camera streams are the real system. The watch runs WearTAK 5.8.4 build p578, the newest release, built from the same code as the one on our own wrist.
How it works
Three things, that's all
-
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.
-
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.
-
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 need help, you reach Andrew himself, not a call center.
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.
Radio tags, no signal needed
runningSmall 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
runningAsk it in plain words: "where's Dad?", "circle the campsite", "route me back to the truck". It answers and draws it on the map. It even carries its own emulated phone and watch on the team, so it tests everything the way you'll use it.
What's happening around you
runningLive aircraft from our own receiver, wildfires, earthquakes, freeway incidents and traffic cameras, on the same map as your people.
Taught by a person
runningWe 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
coming soonCar-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 caseGates, 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
Families, patrols, crews and teams
The same system the military, firefighters and search teams use, set up and sized for you.
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.
