The goal is to turn my existing, fully-functional website into a straightforward mobile application that runs smoothly on both Android and iOS. I need the app to mirror three core website features: secure user login tied to the current account system, a payment flow, and incorporate functions already amde on the website. A cross-platform approach, Flutter is preferred for simplicity, React Native should work, as long as the final build meets Google Play and Apple App Store requirements. Whatever the stack, clean, well-commented code and a maintainable project structure are essential. Deliverables • Source code for both platforms • Release-ready APK and IPA • Clear setup/read-me so I can reproduce the builds • One brief post-handover round for critical bug fixes Everything in the app should talk to the existing backend - no new APIs are necessary. A familiar, consistent look and feel is important, but I’m not expecting pixel-perfect replication; seamless function comes first.
