About this app

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.

What else you can do in the WHOOP app:

• Dig into the details: See a breakdown of your activities by heart rate zone, and even see trends across Sleep, Strain, and Recovery up to 6 months at a time to adjust your behaviors, training, plans and more
• Join a team: Stay motivated and accountable by joining a team. Chat directly with your teammates in the app, or as a coach, see how your team's training is going
• Health Connect: WHOOP integrates with Health Connect to sync activities, health data, and more for a comprehensive view of your overall health.
• Get help: Membership Services is available to answer your questions directly from the app

The app is great and shows awesome data. I think the problem is that garbage in data leads to garbage out analysis. I have a Fitbit and Garmin which both provide more realistic heart rate data (e.g., whoop will show a HR of 150 where I am barely winded). This HR inaccuracy leads to my strain score being off the charts and my recovery never nearing that inaccurate strain. I contacted customer service multiple times and I got troubleshooting advice that doesn't fix a bad sensor.

We have love/hate relationships with this device. I love some functions, but I hate another. I use it only to track my sleep, and I absolutely don't care about fitness aspects of it. But the app is programmed to push you to wear it all the time to provide you with full potential of data and results. So, they have very annoying notifications throughout the day to remind you that you forgot to wear it. Also, they're pushing a "coach" funct. to teach you and guide you on your recovery (read more..)

First rate analysis and data! BUT I use an ad tracking blocker, and the app is constantly trying to track me through Google, Segment.io and Iterable to the tune of 10s of thousands attempts a day. It never gives up. By far, the worst offender on my phone by a factor of 20. Developer, please do what other apps do and limit your attempts? If I gave up every app because they tracked me, I wouldn't have any apps. If you're being blocked, recognize that limit your attempts.
