PRIVACY-FOCUSED

No account required. No central message server.

Built for families, hiking, camping, outdoor adventures, travel, volunteer teams, festivals, and other off-grid situations.

COMPATIBLE HARDWARE REQUIRED

Off-grid communication requires MeshCore-compatible LoRa hardware. Download maps before heading out.

Location updates and message delivery depend on your devices, radio conditions, terrain, positioning availability, and permissions.

Help requests are sent to your Nelos teams, not emergency services. Nelos should not be your only means of communication or safety in critical situations.
