Features
Everything You Need
Past the Last Cell Tower
Smoke Signal replaces the gear bag full of radios, paper maps, and hope. One app, one tracker, total group awareness.
Live Group Map
See every member of your group on a real-time map with GPS breadcrumb trails. Know exactly where everyone is, even deep in the backcountry.
Encrypted P2P Chat
End-to-end encrypted messaging over peer-to-peer connections. No servers, no cloud, no middlemen. Messages are location-tagged so your group always has context.
Emergency SOS
Triple-press the tracker button to instantly broadcast an emergency alert with your exact GPS coordinates to every connected group member.
GPX Import & Export
Import routes from GPX files or record your own with live elevation tracking. Export any route with full waypoint and elevation data to share with your group.
Weather Overlay
Live weather conditions layered right on your map. Make smarter decisions about when to push forward and when to find shelter.
Your Data, Your Device
All data lives on your device. No accounts, no cloud sync, no telemetry. Granular controls let you clear chat history, location data, or everything at once.

Built For
Wherever the Signal Drops
Designed for anyone who ventures beyond cell coverage with a group they need to stay connected to.
Hiking & Backpacking
Split up on the trail without losing track. Regroup faster. Know who's ahead and who's behind without shouting into the wind.
Backcountry Skiing
Track your group across runs and bowls. Record lines for later. SOS if something goes wrong on a steep face.
Camping & Hunting
Keep tabs on your campsite, mark points of interest, and message the group without relying on spotty radio coverage.
Paddling & Water Sports
Stay connected across open water where cell service is nonexistent. Track drift, share locations, coordinate meetups at the takeout.
Search & Rescue
Coordinate field teams with real-time positions and messaging. SOS alerts with GPS ensure rapid response when seconds matter.
Remote Work Sites
Track crew positions across large job sites with no infrastructure. Offline comms keep operations running without cell towers.
