Whoop App

WHOOP monitors your sleep cycles, debt, performance, and quality, to help you know how much sleep you need every night.

WHOOP measures and accumulates your training activities and daily effort with a Strain score that helps you understand when to rest or push.

WHOOP analyzes your key metrics like HRV and resting heart rate to determine a daily recovery score, and shows you how specific lifestyle and training behaviors affect Recovery.

WHOOP now measures your blood oxygen levels, skin temperature, heart rate, and more, so you can see when you’re making progress, or when something’s off your baseline.

WHOOP measures your stress level in real-time using HRV and heart rate. Stress Monitor gives you a personalized stress score from 0 to 3 and suggests science-backed breathwork sessions to either increase alertness or relaxation.
