Who founded WHOOP?
Our founder, Will Ahmed, was a collegiate athlete who wanted to know how training was impacting his body. After reading 500 medical papers, the research revealed that monitoring key metrics 24/7 did more than just optimize training— it could help you feel better, perform better, and live better.
What makes WHOOP different?
WHOOP only measures the metrics scientifically proven to make a significant impact on your physical and mental health. WHOOP delivers over 99% heart rate and HRV tracking accuracy and gold-standard sleep tracking.
Product Description
![the only wearable focused on science backed metrics](https://m.media-amazon.com/images/S/aplus-media-library-service-media/bde00ebe-eca4-4fce-957d-02ebcde2e235.__CR0,0,1464,600_PT0_SX1464_V1___.png)
What is included with my purchase?
Your purchase includes the WHOOP 4.0 device with Onyx SuperKnit band, a waterproof and wireless battery charger and charging cable, as well as a 12-month WHOOP membership and access to the WHOOP app.
Why do I need to enter a credit card to activate my membership when I've already paid?
Your purchase includes your upfront 12-month membership, you will not be charged during activation. At the end of the 12-months, you will have the opportunity to renew/extend your membership directly with WHOOP membership services.
What if my packaging looks different than the packaging in the description?
All genuine WHOOP 4.0 products come in retail-specific packaging as pictured above with the 12-month membership noted on the back of the box. If the box received is different, the inclusion of a 12-month membership with the product is not guaranteed.
I just received my WHOOP 4.0, how do I charge my WHOOP for set up?
Plug your battery pack into a power source using your WHOOP-provided USB-C cord. Your battery pack is fully charged, the LED turns green. Once the battery pack is fully charged, slide it over the WHOOP 4.0 to charge the sensor before set up.
I'm having issues with my WHOOP 4.0, who can I reach out to?
You can reach out to our Membership Services team regarding any hardware or subscription issues. They can be reached 24/7 on the WHOOP app or via support on the WHOOP website. Please reach out to Amazon directly for any issues with shipping or return

I’m hooked!
Only get this if you are serious in knowing what you need.
Customer service was slow to respond, but they finally made it right. They sent me a new sensor and battery, and both work perfectly! I am changing my review from 1-star to 5 because I love my Whoop now!
Original review:
The battery pack will not charge the sensor unless I remove the band - see the attached picture showing that the sensor shows that it is charging, but the percentage of charge keeps dropping until the battery dies. I tried contacting customer service, but trying to resolve the issue with them is beyond frustrating. Customer service replied to my emails just once a day at best, and each time it was from a different agent that clearly did not read the history of troubleshooting already done. The only way I can charge the sensor is to remove the band, which is not the way it's supposed to be used (you're supposed to be able to wear it while it's charging), but customer service seems satisfied with that solution. Count me extremely disappointed.

I compared it to my Garmin watch which I wear continuously on my other wrist and it is always quite off by sometimes as much as 20 bpm more (or less) than the Garmin. I did also the exercise on purpose with my Fitbit which I had stopped wearing to use the Whoop and same result: the Whoop is always pretty off by a considerable difference in bpm.
I voluntarily did the exercise several times to compare the Fitbit with the Garmin and they are synced like a charm, hardly a couple of bpm difference between them or a second or 2 of delays between them. The Whoop issue is a whole other level!
I unfortunately missed the support window of 3 months which I was not aware of until i finally decided I need to get in touch with the seller for a solution... Overall pretty disappointed with my experience, and although I had heard some good opinion about it, there are not much people in KSA that are also wearing one to compare... not sure what I can do anymore about it.

Ich befinde mich aktuell noch in der Kalibrierungsphase, trotzdem gibt mir die App schon rechte gute Einblicke und ist sehr umfangreich, wenn auch etwas unübersichtlich.
Das Band trägt sich recht angenehm, vorallem das es aber keine Display oder sonstige Interaktionsmöglichkeit hat empfinde ich als positiv. So kommt man nicht ständig in Versuchung, etwas darauf zu tun. Parallel dazu trage ich auch noch eine Huawei SmartWatch, welche ich nun aber immer öfter ablegen (kann).
Der größte negative Punkt ist aber, dass ich im Schichtdienst arbeite und mir einmal mehr vor Augen geführt wird, wie unregelmäßig und wenig Schlaf ich phasenweise bekomme (wofür das Whoop aber natürlich nichts kann).
Schön wäre es auch noch, wenn man in der App die Herzfrequenz in Echtzeit in einem Diagramm anzeigen lassen kann. Leider geht das nur während einer Aktivität, zumindest laut meinem jetzigen Wissensstand.
In der App sind auch unzählige Übungen integriert.
Insgesamt ist der Preis für das Abonnement schon happig, mit allem was aber geboten wird empfinde ich ihn als gerade noch angemessen.
Der Preis für das Zubehör ist aber definitiv zu hoch, 50€ für ein Armband ist schon extrem.
