WHOOP integrates Natural Cycles fertility

WHOOP has added a Natural Cycles integration that lets eligible members use overnight temperature data from compatible WHOOP devices inside the FDA-cleared Natural Cycles app. The companies said eligible new Natural Cycles users will receive a 12-month subscription as part of a WHOOP membership, expanding a women’s health offering that WHOOP had already been building through menstrual-cycle features. WHOOP announced the integration on August 4, and the partnership was reported again on August 6 by HLTH. ### Which WHOOP users actually get the new fertility integration? WHOOP’s current membership pages say the Natural Cycles integration is included across its listed plans, and the company is promoting “1 year free of Natural Cycles” for eligible users. WHOOP’s plan page also says the complimentary access is tied to an active WHOOP membership and ends if that membership becomes inactive, after which standard Natural Cycles subscription fees apply. (businesswire.com) Natural Cycles says the free year applies to first-time Natural Cycles users who activate through WHOOP. The company describes the offer as a way for WHOOP members to access Natural Cycles on WHOOP, rather than a blanket free subscription for all existing Natural Cycles customers. ### Which devices work, and what data is being shared? Natural Cycles says the integration currently works with WHOOP 5.0 and WHOOP MG. (whoop.com) The company’s device page says those wearables can send temperature data collected during sleep into the Natural Cycles app, where the app’s algorithm uses it to generate daily fertility insights. WHOOP and Natural Cycles describe the shared signal as overnight skin temperature data. (naturalcycles.com) That matters because Natural Cycles relies on temperature-based cycle tracking, and the new setup removes the need for a separate manual temperature reading for users on supported WHOOP hardware. (naturalcycles.com) ### What does Natural Cycles mean by “FDA-cleared”? Natural Cycles says it is the first app of its kind to receive FDA clearance for planning or preventing pregnancy. WHOOP’s announcement and Natural Cycles’ own materials both describe the product as the only FDA-cleared, hormone-free birth control app. Natural Cycles also says the app is used to provide fertility insights and can support both pregnancy planning and pregnancy prevention, depending on the user’s goal. (businesswire.com) The company’s WHOOP materials frame the integration as a way to “plan and prevent pregnancy” using data from a connected wearable. ### Is this brand-new for WHOOP, or part of a broader push? WHOOP had already been expanding women’s health features before this partnership. (naturalcycles.com) A WHOOP article published in February said its Menstrual Cycle Insights product offers phase-based coaching, biometric tracking and symptom predictions tied to menstrual-cycle phases. The August integration extends that work into fertility and contraception-related use cases through a third-party app with regulatory clearance. (naturalcycles.com) WHOOP’s “What’s New” and membership materials now list Natural Cycles integration among the features available to members. ### What should users watch next? Natural Cycles has already published support pages explaining how WHOOP syncing works and what to do if temperature data does not transfer correctly. (whoop.com) WHOOP is also using its join and membership pages to route users into the offer, including device and plan selection for WHOOP 5.0 and WHOOP MG. WHOOP’s listed U.S. membership prices currently start at $199 per year for the “One” plan, $239 for “Peak,” and $359 for “Life,” with Natural Cycles integration shown across those tiers. (whoop.com) For users considering the feature, the next step is likely to be checking device compatibility and whether they qualify as a new Natural Cycles subscriber before activating the offer.
