A React Native Expo app with a guided 3-step flow: educational intro, an interactive family-tree builder, and a results screen that interprets the inherited hazard H-score and exports a shareable PDF.
Educational mobile app for mapping family cardiac history, calculating an inherited hazard H-score, and exporting shareable PDF reports.
People with a family history of cardiac events often rely on standard risk tools that do not capture how relation, severity, and age at first event combine into a clearer family-history pattern.
Build a mobile-first, easy-to-use family cardiac history tool that helps users record relatives' cardiac events, visualize the pattern in a family tree, calculate an H-score instantly, and share the result in a professional PDF format.
A React Native Expo app with a guided 3-step flow: an educational intro screen that explains the inherited hazard coefficient, an interactive family-tree builder where users tap relatives to add cardiac events with age and severity, and a results screen that interprets the H-score visually, breaks down the score bands, and supports native PDF export and sharing.
Each feature solves a problem the owner or visitors hit before launch. No padding, no nice-to-haves.
Interactive family tree for entering and editing family cardiac history
Automated H-score calculation with visual results interpretation
PDF export and native mobile sharing for taking results to a doctor

Every technology here earns its place, picked for speed of delivery, long-term maintainability, and fit for the specific problem.
We've built health, productivity, and consumer apps in React Native, from one-screen calculators to multi-step guided flows with PDF export.
