- You can build a personal health vault web app without heavy coding by using Cursor's agent mode to scaffold the UI and logic while Terra API handles wearable integrations. Supabase stores the synced wearable data and medical files so the app can show charts and documents.
- The implementation steps are straightforward: get your Terra API key and Dev ID, add environment variables, create endpoints like /api/terra/connect and /api/terra/connections, and configure Supabase as a destination. Then add Terra's MCP (AI interface) so the app can run LLM-powered queries against the health data.
- Combining multi-year wearable data with medical documents and an LLM prompt engine lets you build timelines, strain/readiness scores, and warm-styled graphs to compare biomarkers like HRV, RHR, and VO2 Max around surgical or recovery events. This setup makes it easy to visualize recovery phases and surface correlations between wearable signals and medical records.
