Health Calculators

Start with 10 working, source-linked calculators for adult measurements, resting energy, sleep tracking, home blood-pressure summaries, glucose and A1C conversion, pregnancy dating, corrected age, and smoking exposure. The full 29-section architecture stays visible so future tools have one accountable home; higher-risk sections remain in preparation until their clinical and regulatory gates are met.
