Private Mobile Chat App

I’m putting together a simple, clean-looking chat app focused purely on private one-to-one conversations. The goal is to give users on both iPhone and Android an experience that feels instant and secure, with all the essentials they expect from modern messaging. Core features I need working smoothly: • Text messages • Photos and videos (with preview and full-screen view) • Voice messages that can be recorded and played back in-app Please build it as a single codebase targeting iOS and Android so updates roll out together. Real-time delivery, push notifications, basic user authentication, and an efficient media storage solution should be in place. I’ll need the full source code, setup scripts, and a brief hand-off guide so I can deploy or hand it to another team later. If you’ve already shipped something similar, let me know—speed to a stable MVP is the priority.
