About this app

Connect your phone to MeshCore LoRa hardware and communicate completely off-grid. Send messages, share locations, and stay connected when cellular networks aren’t available.

MeshCore Open is a free, open-source Android app that turns your MeshCore LoRa device into a powerful mesh communication system. It’s built for reliability, privacy, and independence—ideal for remote travel, emergency preparedness, events, or building your own private network.

FEATURES

Off-Grid Messaging
Send and receive text messages over LoRa radio with no cell towers, no internet, and no monthly fees. Messages automatically hop through nearby nodes to reach contacts miles away.

Channels
Join public channels or create private, encrypted channels for group conversations. Great for teams, communities, and coordinated events.

Location Sharing
Share your GPS location with contacts and see everyone’s position on the map in real time.

Interactive Map
View contacts on a built-in map with offline tile caching, so it keeps working even without internet access.

GIFs & Media
Add GIFs to messages when an internet connection is available (optional).

Repeater Management
Configure and monitor MeshCore repeater nodes to extend coverage and improve network reliability.

Background Connectivity
Stay connected while the app runs in the background and receive notifications for incoming messages.

Dark Mode
Full dark theme support for comfortable use day or night.

HOW IT WORKS

OPEN SOURCE & PRIVACY

MeshCore Open is 100% open source.
No ads. No tracking. No data collection.

All messages and data stay on your device and your mesh network. You can view the source code, report issues, or contribute via the project’s GitHub repository.

PERMISSIONS EXPLAINED

Ratings and reviews

I don't understand why when I go into the telemetry settings of a contact it updates the information and location, but the map view shows the same contact in an old location and old update time. Have you tested this ?

I agree that the app is much nicer then the MeshCore app but it constantly crashes and forces me to perform a cashe dump just to open it back up...so I'll go back to the bulletproof MeshCore app that is less polished but has yet to leave me frustrated.

I understand this is work in progress. However, today I have had two false positives - DMs marked with double green checkmarks as delivered, path unknown, but not delivered. I know because both devices are mine. This is one of the worst possible outcomes in communication. I am looking forward to coming back to this app someday, when these issues are solved. The potential is fantastic. Cheers P.S. Specific issue: retry 4/5, double green checkmark confirmation, however no path & did not arrive.
