MeshTrax

MeshTrax is a free, open-source companion app for MeshCore LoRa mesh networking devices. Connect to your radio and send messages across the mesh — no internet, no accounts, and no cloud servers.

Communicate off-grid over long-range LoRa radio — hiking, at an event, in an emergency, or just exploring mesh networking. Your messages, contacts, and keys stay on your device and your own hardware.

Note: MeshTrax is an independent, community-built client and is not the official MeshCore app. It requires a compatible MeshCore device to be useful, it is not a standalone messenger.

A MODERN CHAT EXPERIENCE • Unified inbox, all your direct messages and channels in one clean, messaging-app-style list • Swipe to reply, emoji reactions, and inline GIFs • Delivery status and automatic message retry • Notifications for new messages, even in the background

MESSAGING & CHANNELS • Direct one-to-one messages • Channel and group messaging • Encrypted channels using pre-shared keys

CONTACTS • Add contacts by scanning or sharing QR codes • Organize contacts into groups

MAP & COVERAGE • Nodes, repeaters, and neighbors on an interactive map • Download map areas for offline use • Line-of-sight terrain analysis • Export tracks and points as GPX

DEVICE INSIGHTS • Device and repeater telemetry and sensor readings • Battery monitoring • Message path tracing and routing tools

CONNECT YOUR WAY • Bluetooth Low Energy (BLE) • USB serial (where supported) • Local network / Wi-Fi (TCP)

Plus auto-connect to your last device, light and dark themes, and many languages.

PRIVACY FIRST • No accounts, no sign-up • No ads, analytics, or tracking • No MeshTrax servers — the developer receives none of your data • Block and report tools to keep conversations civil

Optional online features (maps, terrain, GIFs) connect to third-party services only when you use them. See the privacy policy for details.

BUILT ON MESHCORE MeshTrax builds on the open MeshCore ecosystem and is forked from the open-source MeshCore Open client. All credit for the protocol, firmware, and official apps goes to the MeshCore project.

REQUIREMENTS A compatible MeshCore device (a supported LoRa radio running MeshCore firmware).
