Apple Watch Series 8 will give users a better estimate of when they ovulated based on data from new temperature sensors. <\/p>\n

Using two sensors on the Apple Watch Series 8, the built-in menstrual cycle tracking app will check users\u2019 temperature at the wrist every five seconds overnight. This should allow for ovulation tracking since body temperature changes over the course of the menstrual cycle and rises in response to ovulation. <\/p>\n

watchOS 9 and iOS 16 will also include changes to the cycle tracking app that flag any abnormalities in a user\u2019s menstrual cycle based on the data they input about their periods. Deviations from someone\u2019s normal cycle \u2014 like more spotting than usual \u2014 can be a signal of health conditions like fibroids or polycystic ovary syndrome (PCOS), Sumbul Desai, vice president of health at Apple, said during the launch event. <\/p>\n

Apple is pitching its ovulation detection feature as a way to help people who are trying to get pregnant. \u201cIf you\u2019re trying to conceive, knowing if and when you ovulated can inform your family planning with your healthcare provider,\u201d Desai said. <\/p>\n
