MeshTalk Chat

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 • Camera QR code scan to exchange contact keys securely • Simple chat interface with on-device message storage • Automatic key management (stored in iOS Keychain) PRIVACY & SECURITY MeshTalk encrypts messages on your device before sending them. We never collect personal data. Message history remains local on your device. REQUIREMENTS • iOS 15 or later • Bluetooth and Wi-Fi enabled for discovery SUPPORT Questions or feedback?
