Berkanan Lite is a free and open-source Bluetooth-powered group messaging app for iOS, watchOS, tvOS, and macOS.
Broadcast messages anonymously to the crowd around you using Bluetooth. The message range is about 70 meters, but they can reach further because they are retransmitted by receiving apps. *
We believe this service is essential, especially in emergencies. It's enabled by apps joining forces using Berkanan SDK: https://github.com/zssz/BerkananSDK.
* Berkanan Lite for watchOS does not require an iOS companion. Unlike the iOS app, the watchOS and tvOS apps can send and receive messages only while running in the foreground.
