BOSTON, August 4 — WHOOP, the human performance company, today announced an expansion of its women’s health offering through an integration with Natural Cycles° (NC°), the only FDA-cleared, hormone-free birth control app. WHOOP is offering a 12-month subscription to the NC° app to eligible new Natural Cycles users. Members with compatible WHOOP devices can now automatically share overnight skin temperature with the NC° app to enable personalized fertility insights and hormone-free birth control.
The Natural Cycles app, a Class II medical device, uses biomarker data, including temperature and heart rate data, to identify fertile and non-fertile days, helping users prevent pregnancy without hormones while also providing fertility insights. Beyond birth control, the app also supports users through pregnancy planning, pregnancy, postpartum, and perimenopause with dedicated modes tailored to each stage of their reproductive journey.
This integration and exclusive offer advance the efforts of WHOOP in women’s health by combining continuous physiological data with clinically validated fertility technology. Women are one of the fastest-growing segments of WHOOP members, with membership growing 111% year over year. As demand grows for personalized health insights and non-hormonal reproductive health options, this integration gives WHOOP members a more seamless way to understand fertility alongside the recovery, sleep, and health insights already available through WHOOP.
“This partnership represents a commitment to supporting women’s health through clinically-backed, actionable data,” said Dr. Ami Bhatt, WHOOP Chief Medical Officer. “By integrating with the NC° app, we are providing our members with a seamless way to access personalized reproductive health insights, expanding WHOOP beyond performance into everyday health.”
“At Natural Cycles, we’re committed to making digital contraception as seamless as possible for our users,” said Dr. Magda Armbruster, VP of Product at Natural Cycles. “Integrating with WHOOP removes friction from the experience by allowing members to use the wearable they already rely on to automatically capture overnight skin temperature used by the NC° app to determine daily fertility status. It’s another step toward making hormone-free birth control fit more naturally into everyday life.”
Membership Benefits:
- A 12-month subscription to the NC° app included with any WHOOP membership for members new to Natural Cycles.
- Automatic overnight skin temperature sharing with the NC° app through compatible WHOOP devices.

The integration is currently available for users with WHOOP MG and 5.0 devices. WHOOP and Natural Cycles° remain committed to the highest standards of privacy and data security, ensuring that sensitive health information is managed with the utmost care.
