I’m building a wellness application whose core feature is a Metabolic Risk Assessment delivered through a clean, intuitive mobile interface. I need an experienced developer who can take the idea from concept through a functional prototype and into a polished MVP for both iOS and Android. Scope • Design a straightforward onboarding flow where users enter key health data and lifestyle habits. • Implement the Metabolic Risk Assessment algorithm, presenting results in an easy-to-read dashboard with colour-coded risk levels and brief, actionable insights. • Create a secure profile system with optional biometric login. • Set up a lightweight backend (Firebase, Supabase, or a similarly quick-to-deploy solution) to store user data, run calculations, and manage versioned assessment logic. • Build the app with a cross-platform stack such as Flutter or React Native; I’m open to native Swift/Kotlin if you can justify the choice. • Provide UI/UX mock-ups and iterative builds so I can test and give feedback throughout development. • Package a release-ready build, basic documentation, and handoff files for future updates. Nice to have (not required but welcome) – Integration hooks for wearables or Apple Health / Google Fit – Multilingual support – Simple admin panel to adjust scoring thresholds without redeploying the app I value clean code, clear communication, and regular progress demos. If you’ve shipped health-focused apps before or worked with risk calculators, please highlight that experience in your response along with any relevant portfolio links or testflight builds.
