Whoop has expanded its focus on women’s health through a new partnership with Natural Cycles, giving eligible members complimentary access to the fertility and birth control app for 12 months as part of their wearable subscription.

The collaboration enables compatible Whoop devices to automatically send overnight skin temperature readings to the Natural Cycles app, eliminating the need for users to manually record their basal body temperature each morning.

The integration is currently available for owners of the Whoop MG and Whoop 5.0 wearables, providing seamless reproductive health tracking alongside the platform’s existing fitness and recovery features.

Eligible members who are new to Natural Cycles will receive a one-year subscription to the app at no additional cost. Natural Cycles is recognised as the only hormone-free birth control app that has received clearance from the US Food and Drug Administration (FDA).

Using physiological data including skin temperature and heart rate, the app identifies fertile and non-fertile days, helping users either prevent pregnancy or plan conception without hormonal contraception.

The platform also supports women through other stages of reproductive health, offering dedicated features for pregnancy planning, pregnancy, postpartum recovery and perimenopause.

The announcement highlights Whoop’s broader shift towards comprehensive health monitoring rather than focusing solely on athletic performance. The company said women have become one of its fastest-growing customer groups, with female memberships increasing by 111 per cent over the past year.

According to Whoop Chief Medical Officer Dr Ami Bhatt, integrating Natural Cycles allows members to access personalised reproductive health insights while expanding the wearable’s role beyond sports and fitness tracking.

For Natural Cycles users, the partnership simplifies daily fertility monitoring. Instead of taking manual temperature readings every morning, compatible Whoop wearables automatically collect skin temperature data overnight and securely transfer it to the app, which then calculates the user’s daily fertility status.

Both companies said users’ health information will continue to be managed under their existing privacy and security policies.

The partnership reflects a growing trend across the wearable technology industry, with manufacturers increasingly adding women’s health capabilities to devices that were once designed primarily for activity, sleep and heart-rate monitoring. By combining continuous biometric tracking with clinically validated fertility technology, Whoop is broadening the scope of its health ecosystem to include reproductive wellness alongside exercise recovery and overall wellbeing.
