What WHOOP measures

Track every step of your health & fitness journey

Performing every day requires an understanding of the relationship between your physical exertion, mental load, and your body’s ability to bounce back. From sleep to stress, and steps to recovery, WHOOP captures everything to coach you towards your best performance.

Get your best sleep

Sleep is more than time in bed

Improve recovery, boost your immune system, and make performance gains with better quality sleep. WHOOP measures all four types of sleep with lab-level accuracy, and will suggest optimal bedtimes based on what your body needs to recover.

Recovery

Be ready to perform your best

The WHOOP Recovery Score measures how your body is adapting to the stresses of training, lack of sleep, illness, or your menstrual cycle. The more recovered you are, the more your body is signaling it’s ready to take on more. The less recovered you are, the more your body is telling you it’s best to take it easy.
