PeerDrop

PeerDrop lets you share files, chat, and make voice calls directly between devices on your local network — no internet, no cloud, no accounts required. KEY FEATURES - Direct File Transfer: Send photos, videos, documents, and any file type directly to nearby devices. Files are chunked and verified with SHA-256 hashes for integrity. - Encrypted Chat: Send text messages, photos, videos, and voice messages with end-to-end encryption. All chat history is stored locally and encrypted with AES-256-GCM. - Voice Calls: Make crystal-clear voice calls using WebRTC, fully integrated with iOS CallKit for a native calling experience. - Device Discovery: Automatically find nearby devices on your Wi-Fi network using Bonjour. Or connect manually by IP address. - Multi-Connection: Connect to up to 5 devices simultaneously. Each connection has independent chat, file transfer, and voice call capabilities. - Device Library: Save frequently connected devices for quick reconnection. Organize them into groups. - Privacy First: No servers, no accounts, no tracking. Everything stays between your devices. All connections use TLS encryption with trust-on-first-use verification. HOW IT WORKS 1. Open PeerDrop on two devices connected to the same Wi-Fi network 2. Devices discover each other automatically 3. Tap to connect — the receiving device approves the connection 4. Start sharing files, chatting, or making voice calls SECURITY - TLS-encrypted connections with ephemeral P-256 key pairs - AES-256-GCM encryption for stored chat data - Certificate fingerprint verification (trust-on-first-use) - SHA-256 file integrity verification - No data ever leaves your local network
