Push-to-talk, a live team map, navigation, live video and SOS — one app that keeps your whole team talking, seen and aware, wherever they operate.
Coordinating a team on the move usually means juggling a radio, a paper map and a nav app — none of them talking to each other. Terraxi folds voice, the live map, navigation, video and alerts into one shared picture, so everyone knows what's happening the moment it happens.
Multi-channel push-to-talk. Hold the button and the whole channel hears you — from the lock screen, or a Bluetooth PTT button on your chest.
Your whole team, live on one map — positions, presence, pins and shapes. The shared picture updates the instant something moves.
Plot a route or record the trail, then follow the line — while you're still talking and still watching the team move around you.
Zello can talk. ATAK can map. DMD2 can navigate. Terraxi does all three — together.
Push-to-talk the way radio should work — instant, hands-free, impossible to miss. Monitor every channel you're on at once, and transmit on the one that matters.


See where every teammate is in real time, drop the markers that matter, and keep the whole group reading from one shared picture of the ground.
Build a route, import a GPX track, or record the way as you go — then follow it with live position, heading and altitude, without ever leaving the channel.


Stream from your camera straight into the channel and pin it to the map, so the team can read the situation instead of just hearing about it.
The same voice, map and navigation — reframed for the way your team actually works.
First response · search & rescue · emergency services
Priority voice, live positions, and an SOS that breaks through Do Not Disturb — the coordination layer for high-stakes response.
Security teams · event staff · guarding · patrols
Run a site or an event without a bag of radios — every guard on one channel, every position on one map, help one hold away.
Motorcycle clubs · hunting parties · cycling · hiking
Keep the whole group on the map when the trail splits — talk hands-free, share the route, and home in on anyone who drops back.
Sites · utilities · industrial & field crews
Coordinate crews across a wide area — mark hazards and zones on the shared map, reach anyone in a tap, and keep a record of every call.
Boating · sailing · coastal ops · marine rescue
Native nautical units, live positions across the fleet, and private team voice that keeps the working chatter off channel 16 — awareness from shore to horizon.

Comparison reflects each product's core focus, not a feature-by-feature audit. DMD2 is Android-only; ATAK's civilian build is Android-first.
