Terra API is the connectivity layer for health apps. It’s a unified API that connects apps to 1000+ wearable devices, sensors, and health sources - Apple Watch, Garmin, Fitbit, Oura, Whoop, Google Fit, Samsung Health, Eight Sleep, Polar, COROS, and dozens more - normalizing everything into a single schema covering 500+ health metrics. Beyond raw data, Terra offers health scores (recovery, strain, stress, immunity), blood lab integrations (home kits and phlebotomy for hormones, vitamins, cholesterol, glucose), and engagement tools (rewards, streaks, gamification). The platform is HIPAA, GDPR, and CCPA compliant, with SOC 2 Type II certification.
