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.
