This continuous monitoring is crucial because basal body temperature changes are often minute – typically only a few tenths of a degree Fahrenheit – and can be influenced by various factors. WHOOP’s advanced sensors and algorithms are designed to filter out noise and provide accurate, consistent temperature readings.
Upon syncing their WHOOP device with the Natural Cycles app, members grant permission for their overnight skin temperature data to be automatically shared. Natural Cycles’ proprietary algorithm then processes this data alongside other user-inputted information (such as period dates) to determine daily fertility status. The algorithm is designed to learn a woman’s unique cycle patterns over time, becoming more personalized and accurate. By automating the temperature input, the partnership significantly reduces user error and manual effort, which are common challenges with traditional BBT methods. This automation is particularly beneficial for consistent adherence, a key factor in the effectiveness of any birth control method.
It is important for users to note that this integration requires specific WHOOP hardware: either the WHOOP 5.0 band or a WHOOP MG device. These are the latest generations of WHOOP technology, featuring enhanced sensor capabilities necessary for accurate and reliable skin temperature measurement suitable for medical device integration. This requirement ensures that the data fed into Natural Cycles meets the necessary quality standards for an FDA-cleared application. The seamless data flow means that users wake up, and their fertility status for the day is already updated in the Natural Cycles app, allowing for immediate planning and decision-making without the need for additional steps.
