Hi, Looks like you need a working demo first before building out the full billing app — makes sense to test the foundation before going further. I'd use Flutter so it runs on both iOS and Android from one codebase. Simple login and registration screens, email and password auth, everything talking to a live backend so the API calls are clear and easy to follow. Clean code with comments so you can understand what's happening at each step. Full source code, README, and test builds for both platforms included. Quick question — you mentioned two interfaces for the billing software. Is there more planned beyond the login flow, or is this just to validate the auth before building the rest?

Hi, I understand you need a simple cross platform demo app that runs on both iOS and Android with a working login and registration flow connected to a live backend. The focus will be clean code, clear API communication, and an easy setup so you can run and test the project locally. Our team can build this using React Native since it allows a single codebase for both platforms and makes the authentication flow easy to demonstrate. The app will include simple login and registration screens, email and password authentication, and a backend connection using either Firebase Auth or a lightweight REST API. All API requests will be clearly structured and commented so the authentication process is easy to follow. The project will include the full source code in a shared repository, a clear README explaining environment setup and how to run the project on iOS and Android simulators, and built test binaries such as APK and TestFlight ready build so you can test the sign up and sign in flow directly. Happy to discuss the setup and start right away.
