Stolo is a free encrypted messenger that keeps working off the grid — text, files, voice, GPS, and an emergency SOS over a self-configuring mesh of Wi-Fi, cellular, and TCP. No account. No servers. No dead zones.
A single message can cross Radio, Wi-Fi, cellular — and any other link you add. The mesh picks the best medium for every hop and stitches them together without you noticing.
Radio · 915 MHz · 17 dBm · up to 14 km
Wi-Fi mesh · 2.4 GHz · 140 Mbps
Cellular · LTE B12 · backhaul
Download the free app and you're on the mesh. No account, no sign-up, nothing to configure.
Get Stolo free from the App Store. It's accountless — no sign-up, no email, no cloud company in the middle.
Nearby devices discover each other and form a mesh on their own — over Wi-Fi, cellular, or TCP. No pairing codes, no server.
Use Stolo like any messaging app — chats, groups, files, voice, and live location — except it keeps working past the edge of coverage.
Cellular and satellite are great where they work — we're not trying to replace your phone. Here's where Stolo wins, and where another stack is the right call.

The properties that make Stolo work when nothing else does.
Not fallbacks. The mesh picks the best medium per packet and switches mid-session.
Wi-Fi · cellular · TCP/IP · Ethernet · optional LoRa radio (BYO RNode over Bluetooth)
No central server, no dispatch. When any link drops, the mesh re-negotiates its own paths automatically.
Your identity lives on your device. There's no cloud account and no company in the path.
Keys live on the devices. Not on our server — not on anyone's.
Per hop with an optional, bring-your-own LoRa RNode radio over Bluetooth. Chains for longer reach.
Broadcast an SOS with your position to everyone on the mesh, even with no signal to a tower.
Messages queue on-device, signed and sealed. They deliver the instant the recipient comes back within reach — hours or days later, unchanged.
Peers share position over the mesh. See your people on the map even when no cell tower can.
If you're weighing Stolo against a radio, satellite, or a consumer chat app, these are the questions we hear — in order.
The app is free for everyone. For teams that need managed deployments and radios, we're building Stolo for organizations and Hardware-as-a-Service — this offering is early, so let's talk about what you need.
We're working with mining, police & public safety, cities & municipalities, first responders, maritime, and construction. Managed radios and relays (Hardware-as-a-Service) are in development — no shipping catalog yet, no pricing page. Tell us about your site and we'll scope it with you.
Stolo is free on the App Store — no account, no catch. Download it and try the mesh.
