This project centres on building a brand-new utility application that launches simultaneously on Android and iOS. The core idea and feature list are finalised on my side; once we agree to work together I will provide wireframes, user-flow diagrams, and the API documentation you’ll be integrating with. Scope • Develop the full mobile app for both platforms—feel free to use native Swift/Kotlin or a cross-platform framework such as Flutter or React Native if it suits performance and maintenance needs. • Implement a clean, responsive UI that matches the supplied designs. • Connect to our REST endpoints, handle basic offline caching, and integrate Firebase Analytics for usage tracking. • Package and sign release builds ready for submission to the App Store and Google Play, including store-listing assets generated from the final UI. Acceptance criteria – All screens function on iOS 15+ and Android 11+. – No critical or reproducible crashes in TestFlight / internal testing tracks. – Source code passes code-review and ships with concise README and build instructions. When you reply, please include links to past work that best represents your cross-platform utility apps—clean codebases and polished UI/UX are what I study first. If that fits your wheelhouse, I’m keen to share the full brief and timeline.
