Fifty-three percent of smartwatch owners in the U.S. are women, though men “over-index” on everything else, including glucose monitors, smart rings, connected blood pressure cuffs and smart scales. Rock Health’s 2025 Consumer Adoptions Survey says 57% of adults own a wearable of some sort, and ownership is higher among racial and ethnic minorities (64%, compared to 54% of white respondents). Yet gaps persist, particularly for women. “Most wearables filter female physiology data out as noise,” says Jenny Duan, co-founder and CEO of New York City-based Clair Health. “The cycle is technically a fifth vital sign, and yet no consumer device to date has been able to continuously track hormonal data.”
