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
