Now with an on-device AI Coach that answers your health questions using local artificial intelligence. Your comprehensive MyBioAge Index™ combines 12 core health metrics; VO₂max, HRV, Recovery Capacity, Resting HR, Walking HR, Sleep Duration & Regularity, Active Energy, and more; into a single biological age score. Every Monday morning, you'll get an in-app digest highlighting what changed and why. Premium iOS 26 design, elegant charts, and privacy by default. On-device AI Coach - Ask questions about your health data and get instant, personalized insights powered by AI running entirely on your iPhone. No servers, no cloud, complete privacy. Ask "What's my current VO₂max?", "Why did my HRV drop?", "How can I improve sleep?", or "What changed this week?" and get natural, easy-to-understand answers based on your actual health history. Know your biological age - MyBioAge Index™ combines 12 scientifically-weighted health metrics to give you a comprehensive biological age estimate based on your actual health data. Key Metrics Dashboard - Four essential metrics displayed in an elegant visualization: Recovery Capacity (cardiovascular recovery readiness), Training Load (activity balance with zone indicators), Stress Resilience (how well your body handles stress), and Circadian Alignment (daily rhythm health). Tap any metric for detailed breakdowns showing exactly what's driving each score. Apple Watch companion - Glanceable bio age on your wrist. Monday morning insights - A clean, in-app digest arrives every Monday at 10 AM, summarizing Mon-Sun changes and top drivers (e.g., "↑ HRV," "↓ Sleep"). Reasons, not just numbers - See which metrics moved your biological age up or down so you can act with confidence. The AI Chat Assistant can explain why changes happened and what actions to take. Advanced precision - Track Blood Pressure with an external monitor for enhanced accuracy. BP adds 10% additional weight when available—purely additive, no penalty if not tracked. Pacemaker support - Specialized mode for pacemaker users that excludes fixed HRV values and intelligently redistributes weight to other cardiovascular metrics.

Pace by Athlytic reads your Apple Watch health data and tells you what actually matters -- in plain language, not just charts and numbers. Most health apps overwhelm you with scores, rings, and graphs. Pace takes a different approach. It monitors 35+ health signals, learns what's normal for you, and only speaks up when something is worth your attention. HOW IT WORKS Just wear your Apple Watch. Pace does the rest. No data entry required, no numbers to interpret. Each day, Pace checks your health data and gives you a clear summary of how you're doing. WHAT PACE TRACKS Sleep - Duration, quality, efficiency, and consistency - Deep, REM, and core sleep stages - Breathing disturbance tracking Vitals - Heart rate variability (HRV) and resting heart rate - Blood pressure trends with AHA classification - Blood oxygen, respiratory rate, and wrist temperature Cardio Fitness - VO2 Max tracking with age and sex-adjusted context - Walking heart rate trends Activity - Steps with personalized pacing and goal tracking - Active calories, flights climbed, and standing hours - Time in daylight with weather-aware context Workouts - Automatic detection from Apple Watch - Duration, calories, and heart rate summaries Body Composition - Weight, lean body mass, body fat percentage, and FFMI - Personalized baseline ranges with trend detection Mobility - Walking speed, steadiness, and symmetry - Step length, stair speed, and six-minute walk distance - 8 metrics that research links to long-term health SMART HEALTH INSIGHTS Pace learns your personal baselines over 60 days, then alerts you when something shifts. Instead of showing you a number and hoping you know what it means, Pace explains it: - "Your heart rate variability is lower than usual" - "Your blood pressure trend is elevated -- the AHA considers this Stage 1" - "Your walking speed has declined -- this is one of the strongest predictors of overall health" And when things improve, Pace tells you that too. No open loops -- when a concern resolves, you'll know about it. HEALTH PATTERNS Pace discovers correlations hidden in your data -- like how alcohol affects your HRV, or how daylight impacts your deep sleep. Every pattern is statistically validated and backed by peer-reviewed research. No guessing, no astrology. WHAT MAKES PACE DIFFERENT - Conversational health summaries written in plain English - Alerts you when something needs attention, celebrates when things improve - All monitoring is passive -- just wear your Apple Watch - Personal baselines, not one-size-fits-all thresholds - Weather-aware context for activity and daylight - Every clinical threshold is backed by peer-reviewed research PREMIUM FEATURES - AI-powered health assistant -- ask questions about your data in plain English - Health pattern discovery across 35+ metrics - Smart notifications when something shifts - Step goal celebrations with streak tracking - Weekly health summary notifications - Exportable PDF health reports to share with your doctor - Trend charts for all metrics - Step pacing and detailed concern views - Reads alcohol, caffeine, hydration, and nutrition data from Apple Health YOUR PRIVACY All analysis happens on your iPhone using Apple's on-device AI. No cloud uploads, no accounts, no tracking, no data selling. Your health data never leaves your phone. Pace by Athlytic -- your health, explained.
