Bitchat is a messaging app that operates through Bluetooth mesh networks, allowing users to send messages without Wi-Fi or cell reception. Because of Bluetooth’s technical limitations, this kind of app generally only works at a range of around 100 meters, making it useful for situations like finding friends at a busy music festival where cell service is spotty. However, Dorsey claims that his app has an extended range, relaying messages through peers to extend up to 300 meters, or 984 feet.
Fun to watch Jack go wild with vibe coding.
It'd be cool if this eventually could get the messages to the internet, like what AirTag and FindMy do.
