I need a clean, no-nonsense utility app built from the ground up and released simultaneously on iOS and Android. The working name is “Duit Telefon iPad Baju,” but that label can evolve once we lock the feature set together. Scope • Translate the core idea into a concise product spec and user flow. • Design an intuitive, device-responsive UI that feels native on both Apple and Google guidelines. • Develop, test, and optimise the codebase in a modern cross-platform stack (Flutter, React Native, or another framework you recommend). Native builds are also acceptable if they fit the timeline. • Handle QA, performance tuning, and screen-size adaptation—including tablets. • Package everything for App Store and Google Play submission, complete with metadata and screenshots. Deliverables 1. Figma (or similar) design files. 2. Full source code with clear documentation. 3. Tested release builds ready for both stores. 4. A short hand-over guide covering environment setup, deployment steps, and basic maintenance. Acceptance criteria • Feature set agreed in the kickoff document is fully functional and bug-free. • UI matches approved mock-ups within ±2 px. • App passes store compliance checks on first submission. If the brief sparks questions or you have a smarter technical approach, tell me in your message so we can refine the roadmap before we start.
