Lab results arrive as printouts, PDFs and in portals that differ by provider — and scatter further when you switch labs or move. Node Health brings them into one place you own, your phone: scan, upload, or type in any report, and 150+ biomarkers are matched to reference ranges personalized to your age, sex and, where relevant, life stage. What's different: a doctor-reviewed biomarker database instead of AI-generated content, data encrypted on your iPhone, and core tracking that is free forever.
