Could you build this?
Partial The chat, file sharing, and account UI can be vibe-coded, but end-to-end encryption and real-time voice calls need correct cryptographic protocol implementation and calling infrastructure that a vibe-coded app can easily get subtly wrong.
What it would actually take: Starting from a Signal-protocol-style design via an audited library (e.g., libsignal), the app would need iOS clients, a message relay server, and key distribution that avoids phone numbers. Voice and video calls need WebRTC with TURN/SFU infrastructure. A credible security product also needs expert cryptography review and a third-party audit, which vibe coding cannot replace.
