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
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

Pros:
Detailed Health Metrics: The Whoop Band provides in-depth insights into heart rate variability (HRV), sleep patterns, and recovery. This data is quite useful for understanding how my body responds to workouts and rest.
Comfortable Design: The band is lightweight and comfortable to wear 24/7. It’s also water-resistant, which is great for swimming or showering.
No Display: This might be a con for some, but I appreciate that it doesn’t have a distracting screen. It keeps the focus on health metrics rather than notifications.
Cons:
Subscription Model: The biggest downside for me is the $30 monthly subscription fee. It feels a bit steep, especially when there are other fitness trackers available without ongoing costs.
Battery Life: While the battery life is decent, lasting about five days, I wish it were longer. Having to charge it frequently can be a bit inconvenient.
Limited Features: Unlike other fitness trackers, the Whoop Band doesn’t track steps or have a display for real-time data. This makes it less versatile compared to other options on the market.
Overall, the Whoop Band is a solid choice for serious athletes who want detailed health insights and don’t mind the subscription fee. However, for casual users or those looking for a more comprehensive fitness tracker, there might be better options out there.

Habe das Band jetzt seit 2 Monaten und bin sehr zufrieden.
Tragekomfort, Messwerte und kein störendes Display, dass mich im Büro ablenkt.
Das wirklich Einzige was mich daran stört ist das Stoffband was nach dem Duschen oder Schwimmen noch relativ lange nass ist. Aber selbst dafür gibt es mittlerweile Kautschuk Bänder auf der Whoop Website.
