From Chandra Steele's "If You Have a Uterus, Don’t Buy an Apple Watch" posted Tuesday on PC Mag:
With the Apple Watch Series 8 and the Apple Watch Ultra, Apple has introduced features designed to help women take charge of their reproductive health. Except in the United States, women are no longer in charge of their reproductive health, and there is a risk that those who now are could get hold of the data from an Apple Watch and use it against women who use these features.
At the Apple Event earlier this month, Apple introduced a feature that it said “takes our commitment to women’s health even further.” The Apple Watch Series 8 and Apple Watch Ultra each have two temperature sensors, one on the back and one below the display. Data from these sensors is added to Apple’s existing Cycle Tracking app to indicate and track ovulation. Users can receive notification of possible cycle deviations on their Apple Watch and iPhone.
Additionally, a user can choose to log reproductive health data in the Cycle Tracking app, including sexual activity, ovulation test results, progesterone test results, pregnancy test results, and cervical mucus quality.
Even a fraction of this data could be used to prosecute and jail a woman who terminates a pregnancy in a state that legislates against abortion in the wake of Roe v. Wade being struck down with the Supreme Court's Dobbs decision.
My take: Seems a little far fetched, but I think Steele made her point.
