RoveMesh - The group chat that works when nothing else does

RoveMesh is a handheld messenger that sends encrypted text and GPS positions device to device over LoRa mesh radio — no cell towers, no SIM, and no subscription for device-to-device messaging. Every unit relays for the others, so the network grows stronger with each device; managed RoveConnect base stations extend it further. E-paper screen, physical keyboard, multi-day battery. Prototype stage, built in Québec — we publish what our tests actually show, including the failures.
