Apple Stands to Revolutionize Period Tracking — If It Doesn’t Mess Up

A lot is riding on how much the company is willing to share with the public

Dr. Sumbul Desai, vice president of health at Apple, was met with cheers on Monday during the company’s Worldwide Developers Conference when she announced the tech giant had created a service specifically for monitoring menstrual cycles.

“This one is for you,” Desai said, addressing the women in the crowd. “Cycle Tracking.”

“Knowing more about your menstrual cycle gives you a window into your health, from simply ensuring you’re prepared to understanding your personal patterns and regularities,” she added.

For now, the service is available only to developers, but it’s scheduled for a full consumer release with watchOS 6 this fall. Apple Watch and Apple Health app users will then have the option of inputting data about their menstrual cycle history, such as the date of their last period, length of cycle, and symptoms. The service will use this information to make period cycle and “fertile window” predictions for the user.

“We have very limited information about how Apple intends to proceed.”
