Detailed Introduction
bitchat-android is the Android port of the original iOS bitchat app, offering 100% protocol compatibility for cross-platform encrypted messaging over Bluetooth LE mesh networks. Unlike Signal or WhatsApp, it requires no internet connection for local mesh chats – messages hop from device to device via Bluetooth. It supports channel-based group chats with passwords, private encrypted messages using X25519+AES-256-GCM, and store-and-forward for offline peers. The app features a modern Jetpack Compose UI with Material Design 3, battery-optimized adaptive scanning, and IRC-style commands like /join, /msg, and /who. It uses no phone numbers or accounts, and includes an emergency wipe function. Note: This software has not undergone formal security audit; use with caution.
