Samsung Electronics (KRX: 005930) has announced an update to its calendar-based cycle tracking feature, adding skin temperature measurement capabilities to the Galaxy Watch5 and Galaxy Watch5 Pro.
The new feature will be rolled out gradually through the Samsung Health app in South Korea, the United States, and 30 European markets.
The update is designed to help users better manage their menstrual cycles and overall health.
Hon Pak, vice president and head of the Digital Health Team, MX Business at Samsung Electronics, said the new infrared temperature sensor on the Galaxy Watch5 expands the company's health offerings and provides users with more convenient ways to track and understand their health.
For example, since basal body temperature (BBT) varies with menstrual phases, users can now rely on temperature readings to predict their next period.
The cycle tracking feature is powered by Natural Cycles and integrated with Samsung's sensor technology.
It allows users to track changes in skin temperature, a reasonable estimate of BBT, during sleep directly from their wrist. In addition, the Galaxy Watch5 Series uses infrared technology for more accurate readings, helping users track ovulation and better predict their next period.
Users can select Cycle Tracking in the Samsung Health app to enable the feature, enter their most recent cycle information, and enable "Predict period using skin temperature" in the settings.
The readings collected over the past month are displayed as a graph in Cycle Tracking, showing users their period and predicted ovulation and fertile window.
All data collected is encrypted and stored securely on the user's device.
Cycle Tracking also evaluates symptoms entered in the daily log and provides relevant information and tips based on them.
In addition, the Samsung Health app suggests applicable content to better manage holistic health during cycles, such as guided stretching or meditation classes to reduce stress and improve sleep quality.
