Whoop

WHOOP is the performance optimization system that helps people unlock their potential through unprecedented understanding of their bodies. Founded in 2012 by Will Ahmed, WHOOP has grown from a Harvard dorm room idea to a company used by elite athletes worldwide - including Cristiano Ronaldo, LeBron James, Michael Phelps, Aryna Sabalenka, and Patrick Mahomes. The 24/7 wearable tracks sleep, strain, recovery, heart health, and stress to provide personalized coaching backed by scientific research. What sets WHOOP apart is its obsessive focus on metrics that make the greatest impact on how you perform and feel. The screen-free design eliminates distractions, while the 14+ day battery life ensures continuous monitoring. Members improve key metrics like Sleep, Recovery, Strain, and Healthspan through actionable insights. WHOOP doesn't just track your health - it transforms it, with over 99% accurate heart rate and HRV tracking that helps members make smarter decisions every single day to live better for longer.
