I’m looking to turn an idea for a practical utility into a polished mobile application that runs smoothly on both iOS and Android. The end goal is a single code-base solution—whether that ends up being Flutter, React Native, or another framework we agree on—that can be compiled, tested, and shipped to the App Store and Google Play with identical core features and a native look and feel on each platform. What I already know • It’s definitely a mobile application, not web or desktop. • It must launch on both iOS and Android from day one. • The category is Utility/Tool, so the focus is speed, reliability, and an uncluttered interface rather than social feeds or e-commerce flows. What I need from you • Guidance on choosing the most appropriate tech stack and architecture. • UI/UX mock-ups that translate well across screen sizes. • End-to-end development, including any necessary API integrations and local data storage. • Thorough testing on real devices and emulators, plus help meeting each store’s submission guidelines. • Clear hand-off: source code, build instructions, and all design assets. Acceptance criteria 1. A single, version-controlled repository that builds without errors for iOS (Xcode) and Android (Android Studio). 2. Feature parity across both platforms with consistent performance and UI behavior. 3. Successful submission packages ready for TestFlight and Google Play Internal Testing. 4. Concise documentation so future updates are straightforward. If this sounds like a project you’d enjoy, let’s discuss timelines and milestones so we can bring this utility app to life.
