Samsung Electronics today announced that skin temperature measurement¹ is added to its existing calendar-based Cycle Tracking feature. Galaxy Watch5 and Galaxy Watch5 Pro users can now conveniently get even deeper insights to manage their menstrual cycles and overall health. Starting today, the new feature will be progressively released via Samsung Health app updates² in Korea, the U.S. and 30 European markets.³

“Samsung’s holistic view of wellness has been further advanced by our sensor innovations, delivering in-depth health insights that empower users,” said Hon Pak, Vice President and Head of Digital Health Team, MX Business at Samsung Electronics. “The new infrared temperature sensor on Galaxy Watch5 broadens our whole health offerings, providing more convenient ways to track and understand personal health.”

As people search for ways to forecast their next period, they’re turning to temperature readings to help, since basal body temperature (BBT) varies by menstrual phase. BBT needs to be measured immediately after waking and prior to any physical activity or impact from surroundings. Getting accurate BBT readings requires measurement the first thing every morning, a process that can be inconvenient and sometimes even forgotten. Samsung’s new feature automates this process, making it easier and more convenient.

The Cycle Tracking feature is powered by Natural Cycles. Integrated with Samsung’s sensor technology, it enables users to track skin temperature changes, a good estimate of basal body temperature, during sleep right from their wrist. Galaxy Watch5 series uses infrared technology for more accurate readings, even if conditions of surroundings change. The advanced Cycle Tracking helps users track ovulation and better predict when their next period will begin.

To activate, users select Cycle Tracking in the Samsung Health app, add their most recent cycle information into the calendar and then turn on “Predict period with skin temp” in the settings. Readings collected over the prior month are displayed as a graph in Cycle Tracking, showing users their period as well as their predicted ovulation and fertile window. All collected data is encrypted and stored securely on the user’s own device, giving them more control over their data.

Cycle Tracking also evaluates symptoms entered into the daily log and provides relevant information and tips based on them, such as scheduling a day to relax to address fatigue or exercising gently to relieve premenstrual pelvic pain. In addition, Samsung Health app⁴ suggests useful content to help better manage holistic health during cycles, such as guided stretching or meditation classes to reduce stress and achieve a better night’s sleep — a key to a healthier self.

Samsung Electronics and Natural Cycles today announced a partnership to bring advanced temperature-based menstrual cycle tracking capabilities to the Galaxy Watch5 series — the first time Natural Cycles’ ground-breaking algorithm has been adapted for a smartwatch. This latest partnership combines Samsung’s superior sensor technology with Natural Cycles’ innovative fertility technology to give users more detailed insight into their menstrual cycle.

Galaxy Watch5 users will be able to access advanced cycle tracking through the Cycle Tracking feature, which was recently approved by the Ministry of Food and Drug Safety (MFDS) of the Republic of Korea. The Cycle Tracking feature has also been registered with the Food and Drug Administration (FDA) and complies with CE Marking requirements.¹

“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,” said Dr. Raoul Scherwitzl, co-founder and co-CEO of Natural Cycles. “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.”

Natural Cycles is committed to pioneering women’s health with research and passion, leading the development of innovative fertility technology. It developed the world’s first app that is powered by a proprietary algorithm that uses body temperature and other key fertility indicators to determine each user’s unique fertility status. Natural Cycles leverages its technology and algorithm to power the Cycle Tracking feature available on the Samsung Health app with the Galaxy Watch5 series.

Samsung is leading the next era of digital health monitoring with its’ advanced sensor technology, including the ground-breaking BioActive Sensor. Furthermore, the new infrared temperature sensor enables users to get a more detailed overview by tracking skin temperature changes as well as their menstrual cycle. The temperature sensor uses infrared technology for more accurate readings, even if there is a temperature change in their surroundings or they move while sleeping. With all data encrypted and stored on the user’s device itself, it give users more control of their health data and better peace of mind.

“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,” said Hon Pak, Vice President and Head of Digital Health Team, MX Business at Samsung Electronics. “This is another demonstration of Samsung’s open collaboration philosophy with other industry leaders to create better health experiences.”

The new skin temperature-based cycle tracking capabilities will be available through the Samsung Health app on the Galaxy Watch5 and Watch5 Pro within the second quarter in 32 markets, which includes 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, the U.K. and the U.S.
