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

Absolutely brilliant

I ordered from Amazon (as the leading site said, delays), and it came the next day. 2nd day wearing it, it already shows me my sleep patterns, stress levels, recovery rate, and so much more. It is brilliant for those wanting to improve their health and optimize their performance. You need to wear it for four days to gather all your data, but it already shows me so many insights. Highly recommended!

Good product and easy to understand

I bought this as a birthday gift for my husband. He is quite happy with the product. How good it is in terms of tracking and performance will only be known after some data is collected and compared with his other device. Hope this will help him understand his recovery patterns after long runs.
