WHOOP is a wearable that tracks sleep, strain, recovery, stress, and health biometrics 24/7, providing you with personalized coaching based on your goals to help unlock your best performance. WHOOP is screenless, so all of your data lives in the WHOOP app — for a distraction-free focus on your health. The WHOOP app requires a WHOOP wearable.

WHOOP does more than track your activity — it translates your data into clear next steps. WHOOP captures your biometrics 24/7 to calibrate specifically to your body’s unique physiology, then recommending everything from when to go to bed to what behaviors to adopt to help you reach your goals.

Here's how it works:

Sleep: Every night, WHOOP calculates your sleep performance by measuring the sleep you got
compared to the sleep your body needs. You'll wake up to a sleep score from 0 to 100%. Sleep Planner lets you know when you should go to bed to optimize your performance the following day. Now, with the release of WHOOP 4.0, Sleep Planner can also wake you when you've set an exact time, once you've reached your sleep goal, or when you're fully recovered using a quiet, vibrating haptic alarm.

Strain: WHOOP does more than just track your activity – it measures how much physical and mental stress you put on yourself throughout your day to calculate a daily Strain score ranging from 0 to 21. WHOOP measures both your cardiovascular and muscular load, even quantifying the impact of your strength training, to give you the most comprehensive view of the demands you put on your body. Every day, Strain Target will recommend your optimal target exertion range based on your Recovery score to help you maximize your gains without sacrificing your Recovery.

Stress: WHOOP gives you daily insight about your stress, and science-backed techniques to help manage it. Get a real-time stress score from 0-3, and based on your score, choose a breathwork session to either increase your alertness for performance, or increase relaxation in a stressful moment. See your stress trends over time to identify triggers.

Recovery: WHOOP lets you know how ready you are to perform by measuring your heart-rate variability, resting heart rate, sleep, and respiratory rate. You'll get a daily Recovery score on a scale of 0 to 100%. When you're in the green, you're ready for strain, when you're in the yellow or red, you may want to evaluate your training program.

Behaviors: Track the impact of over 140 daily habits and behaviors, like alcohol intake, medication, stress, and more, to better understand how these various behaviors help or hurt you.

WHOOP Coach: Ask questions about your health & fitness and get highly personalized, specific-to-you answers on demand. Using your unique biometric data, the latest in performance science, and OpenAI's technology, WHOOP Coach generates responses on everything from training plans to why you’re feeling tired.
