best app private Messaging App Development

I’m building a social-media style chat app focused on private, one-to-one conversations. At the heart of the product are fast, reliable text messages plus secure photo and video sharing between users.

Beyond those essentials, I’m aiming for a clean mobile UI (iOS and Android), robust user authentication, message status indicators, push notifications, and the basic profile screens you’d expect in a modern chat experience. Voice or video calling is not required right now, but I’d like the architecture to leave room for it later.

You’re free to propose the stack—Flutter or React Native on the front end and something like Firebase, Supabase, or a Node/Express API with real-time sockets on the back are all welcome options—as long as it delivers low-latency messaging and secure media storage.

Deliverables
• Full source code with clear project structure
• Deployed backend and database (cloud or self-hosted, your recommendation)
• Step-by-step setup / deployment notes
• Brief admin or analytics view to monitor users and chats

Please outline your proposed tech stack, any past chat projects, and an estimated timeline so we can get started quickly.
