WHOOP is a wearable device that offers 24/7 tracking of sleep, strain, recovery, stress, and health biometrics. It provides personalized coaching based on individual goals to enhance performance. The device is screenless, ensuring that all data is conveniently accessible through the WHOOP app, allowing users to focus on their health without distractions. The app, which requires the WHOOP wearable, interprets the collected data to offer tailored recommendations, from sleep optimization to behavior adjustments, to help users achieve their objectives effectively.

The functionality of WHOOP revolves around key metrics such as sleep, strain, stress, and recovery. By continuously monitoring biometrics, WHOOP provides insights into sleep quality, physical and mental strain levels, stress management, and readiness for physical exertion. The device calculates sleep performance, daily strain scores, stress levels, and recovery status to guide users on when to rest, how to manage stress, and optimize performance. Additionally, WHOOP offers features like Sleep Planner, Strain Target, and real-time stress scores to assist users in making informed decisions about their health and fitness routines.

In addition to tracking biometrics and offering personalized recommendations, the WHOOP app allows users to delve into detailed activity breakdowns, join teams for motivation and accountability, and integrate with Health Connect for a comprehensive overview of overall health. Users can also access WHOOP Coach for tailored advice on health and fitness queries. While WHOOP products and services are designed for general fitness and wellness purposes, they are not medical devices and should not be used as substitutes for professional medical advice. The app's features aim to empower users to make informed decisions about their health and well-being based on personalized data insights.
