The WHOOP Life Activity Tracker is the ultimate health companion for those who demand absolute data accuracy. Stripping away the distractions of traditional screen-based smartwatches, it features a clean, minimalist fabric band design powered by a clinical-grade biometric array. Capable of evaluating over 65 biomarkers, it provides an advanced Heart Screener with ECG readings, on-demand AFib detection, and daily blood pressure insights to protect your cardiovascular health 24/7.

On-Demand ECG & Blood Pressure Tracking

Take active control of your heart health. The WHOOP Life band integrates high-end sensors that unlock Electrocardiography (ECG) measurements right from your wrist, allowing you to run an immediate heart screener and generate shareable medical reports. Backed by proprietary algorithms, it delivers continuous **Daily Blood Pressure Insights** and automatic atrial fibrillation (AFib) tracking to identify anomalies before they become critical issues.

The Core WHOOP Metrics: Strain, Recovery, & Sleep

Balance your lifestyle efficiently with personalized baseline coaching. The device monitors your vital signs continuously to calculate your daily Strain Score (cardiovascular and muscular exertion) and maps it directly against your Recovery Score (computed via Heart Rate Variability, Resting Heart Rate, and Respiratory Rate). The smart Sleep Coach tracks your exact sleep stages (REM, Deep, Light) and tells you exactly how much sleep you need to perform at 100% the next day.

Healthspan Analytics & Stress Monitoring

Discover your true inner fitness with the innovative Healthspan Architecture. The app constantly references your biometric baselines to compute your physiological WHOOP Age, letting you know if your cardiovascular system is performing younger or older than your biological age. Additionally, real-time Stress Monitoring tracks your sympathetic nervous system reactions, providing immediate haptic feedback and breathing exercises when your levels spike.

Revolutionary On-Wrist Waterproof Charging

Never take your health tracker off your wrist. The WHOOP Life band features an outstanding 14-day battery life on a single charge. When you need a top-up, simply slide the included **Waterproof Wireless PowerPack** directly onto the band frame while you continue working, sleeping, or working out. Because both the sensor and the charger are fully waterproof, you can charge your device seamlessly while showering or swimming.
