MeshTalk is an offline, end-to-end encrypted peer-to-peer messenger for iOS. It works without servers and without the internet by using MultipeerConnectivity (Bluetooth and peer-to-peer Wi-Fi) to discover nearby devices and establish secure, direct connections.
WHY MESHTALK
• No accounts: Start chatting instantly — no phone number or email required.
• No servers: Messages are sent device-to-device; nothing is stored in the cloud.
• End-to-end encryption: X25519 (ECDH) + HKDF (SHA-256) + ChaCha20-Poly1305.
• Local-only: Works offline for nearby communication (events, remote areas, outages).
• Minimal and private: No analytics, no ads.
KEY FEATURES
• Nearby discovery via Bluetooth / peer-to-peer Wi-Fi

• Automatic key management (stored in iOS Keychain)
PRIVACY & SECURITY
