Interactive Utility App from Screenshots

I have a full set of static screenshots that outline every screen, button, and data field of a small personal utility app I want to keep on my own devices. Your job is to transform those images into a fully functioning mobile application that feels native on both Android and iOS. The app itself is simple in concept but must be completely clickable. Each screenshot represents a screen you will recreate, wire together, and make responsive so I can move from one section to another exactly as the images suggest. Key areas include the Reservation ID lookup, a Services list, and a Job Openings board, each reachable through the menu flow shown in the assets. A built-in camera module is essential: when I point the camera at a document’s QR code, the app should read it instantly and route me to the correct record screen. I will supply sample codes for testing. While I am flexible on the stack (Flutter, React Native, native Swift/Kotlin, or another modern framework you prefer), the final build must run smoothly on my phone and tablet in both ecosystems. Please keep layouts adaptive so they look good on varying screen sizes, and hand over the full, well-commented source along with an installable build and a simple backup copy for safekeeping. Deliverables • Android .apk and iOS test build (TestFlight or .ipa) ready to install • Complete, clean source code with clear project structure • All recreated UI screens fully linked and responsive • Functional QR-scanner tied into the navigation flow • A brief read-me explaining setup, dependencies, and how to restore the backup Acceptance criteria: if I can tap through every screen exactly as the screenshots indicate, scan a sample QR code to land on the correct record page, and run the app without errors on both platforms, the job is done. I look forward to seeing how quickly you can bring these static designs to life.
