For the roughly one billion women worldwide navigating the hormonal fog of midlife, a notification from their iPhone might soon be the first clear signal that something significant is underway. At WWDC 2026 on Monday, Apple announced that its Health app will begin alerting users when logged cycle patterns point toward perimenopause, quietly positioning the company as the largest consumer entry point into one of health tech’s fastest-growing markets.
The update builds on Apple’s existing cycle tracking feature, which the company first introduced to Apple Watch and iOS back in 2019. That tool lets users log menstrual cycle data and fertility information through the Health app. Over time, Apple layered in more capability: with iOS 16 and watchOS 9, the app gained cycle deviation detection, and Apple Watch Series 8 added a wrist temperature sensor to generate retrospective ovulation estimates. The perimenopause feature is the next logical step in that progression, shifting the app’s focus from reproductive planning toward a longer arc of hormonal health.
According to Apple VP of OS Product Management Stacey Ford, the new feature will send notifications “when their cycle patterns are suggestive of perimenopause.” Ford added that users will also be able to log symptoms and access educational content, “so you can understand more about what’s going on with your body and be better prepared to talk to your doctor.
That doctor-readiness angle matters. Perimenopause, the transitional phase before menopause, which can last anywhere from a few years to over a decade, is notoriously underdiagnosed. Symptoms including irregular cycles, sleep disruption, mood shifts, and hot flashes are frequently dismissed or misattributed. A tool that surfaces patterns over time and packages them into exportable data could give patients a more credible basis for clinical conversations. Apple’s existing cycle deviation feature already allows users to export 12 months of cycle history as a PDF to share with a healthcare provider.
The announcement lands at a moment of surging cultural and commercial interest in perimenopause and menopause health. The topic has broken through on TikTok, Instagram, and mainstream television, and the investment community has followed. In February, telehealth platform Midi Health, which centers its care model on perimenopause and menopause, raised $100 million in a Series D round led by Goodwater Capital, achieving a $1 billion valuation. The broader women’s digital health market, valued at roughly $3.66 billion in 2024, is projected to reach $10.74 billion by 2032, according to a ResearchAndMarkets analysis.
By building perimenopause tracking into an app already on hundreds of millions of iPhones, Apple isn’t just entering this market, it’s potentially reshaping it. Dedicated apps like Clue, Flo, and a wave of better-funded telehealth startups have built audiences around this need. Apple’s advantage is that it doesn’t need to acquire users; they’re already logging data. The cycle tracking app’s accuracy improves over time, and after six months of consistent logging, predictions become significantly more reliable.
The stronger signal from 2026’s femtech surge isn’t just that tools exist, but that women’s health is finally being treated with more seriousness, data, and access, helping women identify symptoms earlier and speak to doctors with greater confidence. Apple’s perimenopause feature is, at its core, a bet that the most powerful delivery mechanism for that shift is already sitting in a woman’s pocket.
The new feature arrives with iOS 27 and watchOS 27, expected in general availability this fall.
