Columba is a native Android messaging and voice call app for the Reticulum network, sending LXMF messages and making LXST calls without internet, cell towers, or central servers. It supports multiple transports including Bluetooth LE, WiFi, LoRa via RNode, and TCP, with end-to-end encryption and on-device cryptographic identities.

Use cases

• send encrypted messages without internet or cell service
• make voice calls over a LoRa mesh network
• chat with nearby devices over Bluetooth LE
• share location offline with a map view
• browse NomadNetwork pages over Reticulum
• migrate messaging identities between devices or from Sideband
• communicate during disasters or network outages

When to choose

• you need off-grid, infrastructure-free encrypted communication on Android
• you want to join or build a Reticulum/LXMF mesh with LoRa, BLE, WiFi, or TCP transports
• you value privacy with no accounts, phone numbers, or central servers
• you need offline maps and location sharing in the field

When to avoid

• you need to message people on SMS, WhatsApp, or mainstream networks
• you require iOS or desktop support
