I built the app as a full mobile product using React Native, with a clean navigation flow between the home, reports list, and detailed “Health Research” screen. The heatmap view and risk bars are fully data-driven, rendering values returned from the backend API so users can see low/medium/high risk at a glance. The backend (Node.js + REST API) stores user profiles, DNA report data, and category metadata, and the app fetches and displays this in real time.
