I need complete, production-ready code for a mobile application that runs smoothly on both iOS and Android. The app’s core purpose is to act as a professional observation tool within an educational setting: I should be able to open a session, Log into a series of forced choice decisions, collecting data at each choice, time activities and produce a summary of data. App has been designed but no longer communicates with web. I know nothing about the platforms and I’m flexible on the tech stack—React Native, Flutter, or fully native Swift + Kotlin are all fine as long as the final build is truly cross-platform and maintainable. Clean architecture, clear component separation, and readable naming conventions are important to me; I’ll be reviewing the repository for that. For clarity, here’s what I expect to receive: • Complete source code with clear commit history • A brief README that explains set-up, build, and deployment steps for both platforms • Sample data or seed script so I can verify the observation flow end to end • Light unit test coverage of the critical business logic (session creation, note storage, report generation) The build should open, run, and let me create an observation session in under five minutes on a fresh machine following your README. If that works on both Xcode and Android Studio emulators, I’ll consider the milestone met. The description of how things should be rebuilt is AI generated, I am hoping it means more to you than me
