Bridgefy: Offline Messaging App
Offline messaging app using Bluetooth and mesh networking, forming connections between nearby devices for message transmission over distance
What is Bridgefy?
Bridgefy is an offline messaging application designed to enable communication when internet or cellular networks are unavailable. It utilizes Bluetooth and mesh networking to connect nearby smartphones directly via peer-to-peer connections and relay messages over long distances.
The app allows users to send and receive messages, share locations, and use group chat without relying on traditional communication infrastructure. By spreading connections between devices like a mesh network, messages can traverse distances through daisy chains of linked smartphones.
Bridgefy is promoted for use in emergencies and areas with poor network coverage, allowing people to communicate when infrastructure fails. It has also been used at protests, conferences, and other crowded events to enable proximal communication without network congestion. The app works offline between Android and iOS devices and offers end-to-end encryption for security.
While intended for peer networking, Bridgefy requires that users be within approximately 330 feet to connect directly via Bluetooth. Over longer distances, message relaying depends on a chain of active app users positioned favorably between sender and recipient. Without enough app density, offline range is limited.
