Cross-Platform MVP Concept Test

I’m ready to see my idea in action and I need an MVP that runs smoothly on both the web and mobile devices. At this stage the product only has to do three things well: launch quickly in a browser, install or run seamlessly on iOS/Android, and store/retrieve data reliably. No authentication flows or advanced bells and whistles yet—just a clean, mobile-friendly interface tied to a lightweight database so I can validate core usability and gather feedback. You’re free to choose the stack that helps us move fastest—React + Firebase, Flutter with a simple cloud back-end, even a progressive web app that can be wrapped for the stores—so long as the codebase is structured for easy feature additions down the road. Think of this as the foundation we’ll expand once the concept is proven. Deliverables: • Source code for both web and mobile builds • Deployed web link plus test builds (APK/IPA or TestFlight) • Brief README explaining setup, build, and data schema If you’ve shipped lean products before and can turn around a solid, no-frills release, let’s get started.
