The sexual-activity tracking feature will be included as part of a new “reproductive health” section within Apple’s Health Kit app, which will be available with the iOS9 update. Users will be able to log the day and time that they had sex, and whether they used protection.
Apple’s Health Kit will also allow users to track other measures important for reproductive health, including menstrual cycles, ovulation test results and cervical mucus quality. (Tracking these factors can help a woman know when she’s more likely to get pregnant.)
