WHOOP is a screenless wearable and subscription app that continuously monitors sleep, strain, recovery, stress, and heart health 24/7. Founded in 2012 by Will Ahmed and headquartered in Boston, the company describes itself as "the human performance company" and counts athletes such as Cristiano Ronaldo, Patrick Mahomes, and Rory McIlroy among its partners. Current hardware includes the WHOOP 5.0 band, with a battery life of 14+ days, and the medical-grade WHOOP MG, which adds ECG heart screening, irregular heart rhythm notifications, and daily blood pressure insights (beta).
The app translates raw biometrics into daily recovery, strain, and sleep scores, plus VO2 Max, Healthspan and WHOOP Age (pace-of-aging) metrics, real-time stress monitoring, and hormonal and menstrual cycle insights for women. Members can log 300+ daily behaviors in the WHOOP Journal to uncover what affects their recovery.
WHOOP Coach is the platform's conversational AI coach, which WHOOP states is powered by OpenAI's GPT-4. It answers questions about the member's own biometric data, generates personalized training plans, explains performance science, and identifies patterns across sleep, strain, and recovery, in more than 50 languages.
WHOOP is aimed at athletes and health-conscious users who want continuous physiological feedback rather than a smartwatch. Hardware is included with the membership: WHOOP One costs $199/year, WHOOP Peak $239/year (adding Healthspan, Health Monitor, and Stress Monitor), and WHOOP Life $359/year with the WHOOP MG device and its medical-grade features. The companion app runs on iOS and Android, and a public developer API with OAuth 2.0 and webhooks is available at developer.whoop.com. WHOOP Unite serves teams and organizations.
