Metrya turns Apple Health data into clear, private AI insights. Analyze HRV, sleep, recovery, stress and training directly on your iPhone - no servers, no accounts. 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. Core features (free forever): Apple Health dashboard: Steps, sleep stages, heart rate, HRV, resting HR, SpO2, body temperature, body composition, VO2 max and workouts - 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. Reserve: A body battery that drains as you stay awake and refills only when you genuinely rest. Sentinel: Overnight temperature, resting HR, HRV, breathing and sleep continuity fused into one signal - Clear, Watch or Alert - before you feel it. Weekly Reports: Your week ranked and read back to you - Night, Recovery and Output, each metric sorted by which way it moved. Plus a body composition trend, and BMI shown only beside waist-to-height, body fat and FFMI. Sleep and Training detail: a scrubbable hypnogram with overnight heart rate and a 7-night sleep debt ledger; heart-rate curves, zones and load for every workout. Stress Monitor: Autonomic strain from your Watch's HRV, scored against your own range, not a population average. Smart anomaly alerts: A 30-day personal baseline for 8 key metrics flags significant deviations, correlated with nearby events like alcohol, travel or hard training. Biological Age: Estimated from cardiovascular fitness, sleep quality, metabolic markers and activity level, benchmarked against age-group averages with a plain-language explanation. Set Commitments for steps, sleep, HRV, weight and more, with automatic streaks and badges. Hydration and caffeine tracking, an Apple Watch app with complications, Home Screen widgets and a full Dark Mode. Total privacy: No backend servers. No accounts. Metrya Pro: AI health chat: Ask "How did my HRV trend this week?" or "Why was my recovery so low after that flight?" The AI has full context of your data and answers with specific numbers, not generic advice. Ask about what you're looking at: a workout, a night, a chart, a report - the answer cites what's on screen. Bring Your Own Key (BYOK): Use your own Anthropic, OpenAI or Google API key. You choose the model and control the cost - calls go directly from your device to the provider. Apple Intelligence: private on-device AI analysis (supported devices) On-device models: Gemma, Qwen, Bonsai Recurring Insights: AI health reports daily or weekly, by push notification. Wellness Log: sessions (sauna, cold plunge, breathwork, meditation), check-ins (energy, mood, stress, soreness, focus) and events (supplements, caffeine, alcohol, sunlight, travel). Profile context: Tell the AI your supplement stack, equipment and dietary approach - it personalises every answer. Turn any AI advice into a trackable goal with one tap - extract full Commitments directly from chat 30-day AI context: Full detail for the last 7 days, weekly summaries for days 8-30, with anomalies surfaced automatically. AI-powered Nutrition Log - log meals in plain English and let AI extract macros, calories and micronutrients, plus a Food Reactions ledger of your own patterns Compatibility Works with any device that writes to Apple Health: Apple Watch, Oura, Ultrahuman, Whoop, Garmin, Amazfit, smart scales. Metrya Pro requires Apple Intelligence on a supported device, or your own API key from OpenAI, Anthropic or Google.
