Sideband is an LXMF client for Android, Linux and macOS. It allows you to communicate with other people or LXMF-compatible systems over Reticulum networks using LoRa, Packet Radio, WiFi, I2P, or anything else Reticulum supports.

Sideband also supports exchanging messages through encrypted QR-codes on paper, or through messages embedded directly in lxm:// links.
