Peak Score: Training Readiness for Athletes Peak Score is a training readiness app for athletes who use Apple Watch. It combines sleep quality, Recovery & Vitals, and Training Load into one daily Training Readiness score, so you can decide whether to Rest, Keep Easy, or Push Hard. Instead of leaving you to interpret separate charts and metrics, Peak Score turns your Apple Health data into clear guidance for today and a view of how tomorrow is shaping up. What Is Peak Score? Peak Score helps you understand how recovered your body is and what your current training data means. Each day, it analyzes your sleep quality, Recovery & Vitals, and recent Training Load on your iPhone. You get one Training Readiness score from 0-100 with a clear recommendation: Rest, Keep Easy, or Push Hard. Key Features - Training Readiness — See one daily score built from sleep quality, Recovery & Vitals, and Training Load. Use it to decide how hard to train today. - AI Coach — Turn your Training Readiness, sleep, Heart Rate Variability (HRV), and Training Load into specific daily guidance. AI Coach uses Apple Intelligence on your iPhone when available and enabled. - Training Load — Understand whether you are doing too little, training within your current capacity, or doing too much. Peak Score compares your 7-day Training Load with a 28-day baseline using the Acute:Chronic Workload Ratio (ACWR). - Recovery & Vitals — Review Heart Rate Variability (HRV), Resting Heart Rate (RHR), respiratory rate, personal typical ranges, and trends without having to interpret isolated numbers. - Workout Analysis — Explore Heart Rate Zones from Z1-Z5, Cardio Focus, Training Load for each workout, and workout trends. - 7-Day Training Readiness Trend — See how your Training Readiness has changed over the previous seven days and recognize whether Recovery is improving or declining. - Tomorrow's Training Readiness Prediction — See an estimate of how ready you are likely to be tomorrow based on current Recovery and Training Load data. - Apple Watch companion — Check Training Readiness, Strain, and Recovery from your wrist. Peak Score performs its analysis on iPhone and sends snapshots to Apple Watch. Who Is Peak Score For? Peak Score is built for runners, cyclists, triathletes, gym and hybrid athletes, team-sport athletes, and anyone who trains regularly with Apple Watch. It is for athletes who want a practical answer from their data, not another collection of charts to decode. How It Works 1. Allow Peak Score to read supported data from Apple Health. 2. Wear Apple Watch for workouts and overnight measurements. 3. Peak Score analyzes your data on iPhone. 4. Open Peak Score to review Training Readiness, AI Coach guidance, Recovery & Vitals, Training Load, and Workout Analysis.

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.
