Description
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
Pair your phone with a MeshCore LoRa device via Bluetooth
The app communicates directly with your MeshCore hardware
Messages are transmitted over LoRa radio
Other nodes relay messages through the mesh to reach their destination
Location permission (required by Android for Bluetooth scanning)
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.

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

Much better than the original, adds features that have been sorely needed, and improves others that were fairly bare-bones on the original version.
