Refine AI-Built Mobile App

I already have a first-pass mobile application produced by an AI generator, but it’s rough around the edges and I’d like an experienced developer to give it the polish—and reliability—that only a human can provide. The existing codebase is available and the core concept functions, yet the UX, performance, and overall structure need professional attention.

The end goal is a stable, well-architected release that runs smoothly on both iOS and Android. I’m flexible on frameworks; if you’re most productive in React Native, Flutter, Swift/Kotlin, or another proven stack, let’s use what will produce the best long-term result. There’s no hard deadline, so we can focus on doing things the right way rather than rushing.

Key things I need from you:
• Review the current AI-generated code, identify weak spots, and recommend the optimal approach (refactor vs. rebuild).
• Implement the agreed solution, ensuring clean architecture, responsive UI, and platform-consistent design.
• Provide commented source code, build instructions, and guidance for App Store & Google Play submission.

If you’re comfortable taking an AI draft and turning it into a production-ready product, I’d love to hear how you’d tackle it.
