Samsung Galaxy Watch5 Gets Temperature Based Menstrual Cycle Tracking

Samsung and Natural Cycles have partnered to add menstrual cycle tracking to Galaxy Watch5 using Natural Cycles’ algorithm. The collaboration combines Samsung’s sensor tech with Natural Cycles’ fertility tech to provide users with better menstrual cycle insights. Recently, Samsung also added Camera Controller for Galaxy Watch4 and Watch5 series.

Advanced Temperature-Based Cycle Tracking to Galaxy Watch5 Series

Galaxy Watch5 users can access advanced menstrual cycle tracking through the Cycle Tracking feature, which has been approved by the Ministry of Food and Drug Safety (MFDS) of the Republic of Korea, registered with the Food and Drug Administration (FDA), and complies with CE Marking requirements.

Natural Cycles is a pioneer in women’s health and has developed the world’s first app that determines each user’s unique fertility status using body temperature and other fertility indicators. Natural Cycles’ technology and algorithm powers the Cycle Tracking feature on the Samsung Health app with the Galaxy Watch5 series.

Samsung’s advanced sensor technology, including the BioActive Sensor, and the new infrared temperature sensor, are leading the next era of digital health monitoring. The temperature sensor can track skin temperature changes and menstrual cycles using infrared technology, providing accurate readings even if the user moves while sleeping or the surrounding temperature changes. All user data is encrypted and stored on their device, giving them better control and peace of mind.


The Samsung Health app on the Galaxy Watch5 and Watch5 Pro will offer the new skin temperature-based cycle tracking capabilities in 32 markets, including the U.S., the U.K., Germany, and France, in the second quarter.

The countries are Austria, Belgium, Bulgaria, Croatia, Cyprus, the Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Korea, Latvia, Lithuania, Luxembourg, the Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland, and the U.K.

Speaking on the announcement, Hon Pak, Vice President and Head of Digital Health Team, MX Business at Samsung Electronics, said,

Consumers can now easily track their menstrual cycle right from their wrist, combining Natural Cycles’ innovative fertility technology with Samsung’s superior temperature sensor to provide a more holistic understanding of their health and wellbeing. This is another demonstration of Samsung’s open collaboration philosophy with other industry leaders to create better health experiences.

Speaking on the partnership, Dr. Raoul Scherwitzl, co-founder and co-CEO of Natural Cycles, said,

As a company that’s grounded in science and technology, we are excited to partner with Samsung to deliver a premium experience that pushes women’s health forward. The Natural Cycles app has helped millions of women around the world take control of their fertility and this partnership will allow Samsung to leverage our fertility technology to offer temperature-based cycle tracking through a smartwatch for the first time.
