Use Cycle Tracking on Apple Watch
Use the Cycle Tracking app to log details about your menstrual cycle. You can add flow information and record symptoms such as headaches or cramps. Using information you’ve logged, the Cycle Tracking app can alert you when it predicts that your next period or fertile window is about to start. In addition to using data you’ve logged, Cycle Tracking can also use heart rate data to improve predictions. If you wear Apple Watch to sleep each night, the app can use wrist temperature (on supported models) to improve period predictions and provide retrospective ovulation estimates. For more information, see the iPhone User Guide and the Apple Support article Track your period with Cycle Tracking.
Siri: On supported models, say something like: “Log that my period started today.” (Not available in all languages or regions.)
Note: The Health app is designed to protect your information and enable you to choose what to share. Learn more about how the Health app is built to keep your data secure and protect your privacy.
