Apple Watch uses skin temperature data to estimate the likely day of ovulation after it has occurred and improve period predictions.

Apple Watch could feature a skin temperature sensor to track a woman’s ovulation cycle based on temperature. It’s not a stretch to imagine a future where women receive notifications ahead of time, alerting them of their non-fertile days with a stunning accuracy; and on the opposite end of the spectrum- notifications when they are most likely to conceive.

Apple Watch Series 8 or Apple Watch Ultra uses wrist temperature data to detect the biphasic shift, which is an increase in temperature that often occurs after ovulation. Advanced algorithms use wrist temperature data and logged cycle data to estimate the day ovulation likely occurred.
