Everything You Need
Past the Last Cell Tower

Smoke Signal replaces the gear bag full of radios, paper maps, and hope. One app, one device, 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

Private by design. Messages travel device to device, never to a server or the cloud, and they're location-tagged so your group always has context.

Group Alert

Press the button to instantly ping your whole group with your exact location, so the people closest to you know right where you are.

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.

Weather Overlay

Live weather conditions layered right on your map. Make smarter calls 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. Messages and locations move directly between devices. There's no server in the middle to leak, subpoena, or shut down.

Smoke Signal is not a satellite messenger and does not contact emergency services (911). Group Alert reaches only group members within radio range. For life-threatening emergencies, carry a satellite communicator or ensure cell coverage.

A Year of Building

VINICUNCA, PERU · 5,036 M

I'm Cameron Cooper. I spent the last year building Smoke Signal because keeping a group together off-grid shouldn't require sourcing radio boards and flashing firmware the night before a trip.

I built the app I wanted on the trail, then paired it with hardware that works out of the box. Every release gets tested the same way: real devices, real terrain, in the SoCal chaparral where ridges block line of sight and canyons eat signal.

Field Report · Crystal Cove, CA

Seven miles through coastal chaparral, the kind of place your phone gives up on before you're out of the parking lot. Rolling ridges, deep canyons, no bars anywhere.

I handed the devices out at the trailhead. Nothing to set up, no apps to configure, nothing to plug in. We just started walking.

The whole way out, everyone stayed on the same live map. I could see where the group was without shouting over a ridge or doubling back to find someone. Spread more than a mile apart through the hills, our messages still went through: private, device to device, with no cell service and nobody else in the loop. When a ridgeline dropped between two of us, the message simply hopped through another device to get where it was going. Leaving one device up high at camp stretched the whole group's range even farther.

Nobody had to know how any of it worked. That's the point. It kept the group together where phones quit.

Treat any fixed range number with suspicion, including ours. Range depends on terrain and line of sight, and every device you add extends the mesh. Test with your group before you depend on it.

Tested the way you'll use it. No spam, just the launch email.

No Monthly Fees. Ever.

Satellite messengers cost hundreds up front plus a monthly plan. Smoke Signal is a one-time purchase: buy your devices once and your whole group stays connected, with no subscription. Devices talk to devices, so start with a kit. Every Tag texts through the app on your phone; a Pocket only adds a built-in screen and dramatically longer range.

$189

Group Kit

2 TAGS · PRE-PAIRED

A two-person starter. Two Tags in one box, paired before they ship: enough for a pair to see each other on the map and text through their phones.
