Metrya – Health AI

Metrya turns Apple Health data into clear, private AI insights. Analyze HRV, sleep, recovery, and trends directly on your iPhone - no servers, no accounts, and no subscriptions. With your own Claude / OpenAI / Gemini key, Metrya acts as a personal health and longevity coach, asking “why am I tired?” or “is my HRV trending down?” and answering with data‑grounded advice. Built for privacy, Metrya processes every metric on your iPhone. Your health data never touches our servers, and you always control which AI provider you use. Core features (free forever): Apple Health dashboard: Steps, sleep stages, heart rate, HRV, resting HR, SpO₂, body temperature, body composition, VO₂ max, workouts, and more - synced automatically across the last 30 days. Daily Recovery Score: A 0–100 score calculated on-device from HRV vs your personal baseline, resting HR, sleep duration, deep and REM sleep quality, and 3-day HRV trend. See each contributing factor at a glance. Smart anomaly alerts: Metrya builds a 30-day personal baseline for 8 key metrics. When a reading deviates significantly, you get a colour-coded alert - mild, moderate, or severe - automatically correlated with nearby lifestyle events like alcohol, travel or high-intensity training. Biological Age: Estimated from cardiovascular fitness, sleep quality, metabolic markers, and activity level - benchmarked against age-group averages with a plain-language explanation for each factor and a trend line over time. Set Commitments for steps, sleep, HRV, weight and more, and track your progress with automatic streaks and milestone badges - all included, no Pro upgrade required. Total privacy: No backend servers. No accounts. Metrya Pro (lifetime unlock): One-time purchase. No subscriptions, ever. AI health chat: Ask questions like: "How did my HRV trend this week?" or "Why was my recovery so low after that flight?" The AI receives full context of your recent data and answers with specific numbers, not generic advice. Bring Your Own Key (BYOK): Use your own Anthropic Claude, OpenAI, or Google Gemini API key. You choose the model and control the cost. AI calls go directly from your device to the provider you chose.
