Flo Health introduces perimenopause resources as a survey reveals that 66% of women felt better equipped for puberty.

      **TL;DR** Flo Health, the largest women's health app globally with 80 million monthly active users, is introducing a new set of perimenopause tools for premium subscribers in May 2026. A Wakefield Research survey indicated that 66% of US women aged 38-50 felt more prepared for puberty than for perimenopause. The tools include a Symptom Checker, Perimenopause Score, Menopause Timeline, and Relief Options. Flo's partnership with Mayo Clinic and a study published in Nature support their clinical approach. In 2024, the company became Europe’s first femtech unicorn after a $200 million Series C funding from General Atlantic.

      Two-thirds of American women ages 38 to 50 report feeling better prepared for puberty than for perimenopause. This statistic, derived from a nationally representative survey commissioned by Flo Health and executed by Wakefield Research, highlights a long-standing gap in public health messaging: many women confront one of life’s significant hormonal transitions with less reliable information than they had during their teenage years.

      Flo Health, a period-tracking app that has evolved into the world's largest women's health platform, aims to address this knowledge gap by launching a new suite of perimenopause tools for premium subscribers this month. These features—a symptom checker, a perimenopause severity score, a menopause timeline tracker, and a medically verified relief-options guide—mark the company's most substantial product expansion since achieving unicorn status in 2024.

      **The knowledge gap**

      The issue Flo is addressing is widely recognized. Over a billion women worldwide will go through perimenopause or menopause, yet a recent Flo study showed that one-third of American women aged 35 and older are unsure if they are in perimenopause. This problem contributes to a persistent gender gap in health data that femtech companies strive to bridge. The confusion is intensified by a shift in the information landscape from silence to an overwhelming amount of noise: doctors are advising patients to be cautious of unverified advice flooding social media and wellness platforms as menopause discussions gain popularity.

      The implications of this confusion are tangible, as self-reported in Flo’s Wakefield Research survey. Fifty-two percent of women in relationships indicated that perimenopause has affected their romantic lives, while 48% said it hindered their ability to exercise. These statistics reflect a population grappling with a medical reality without adequate tools, illustrating why Flo views perimenopause not merely as a feature addition, but as a viable market.

      **What the tools do**

      The new suite includes four products, all accessible to Flo Premium users. The Perimenopause Symptom Checker allows users to assess their symptoms against recognized indicators of perimenopause. The Perimenopause Score, touted by Flo as the first scientifically validated digital assessment tool tailored for perimenopause, provides a severity rating and tracks changes. The Menopause Timeline offers insights into a user's position within the broader hormonal transition. Finally, Relief Options presents a medically verified comparison of treatment options, ranging from medications to lifestyle changes, aligned with specific symptoms.

      These tools are based on content created in collaboration with over 100 medical experts. Anna Klepchukova, Flo’s chief medical officer, positioned the launch as a response to an information crisis rather than a mere gap in features. She emphasized that women don’t lack access to perimenopause content; they struggle to differentiate verified medical advice from the barrage of conflicting narratives that have emerged as the topic gains visibility.

      **The research behind it**

      Flo has been preparing for this launch for over a year. Its science team published findings in the Nature portfolio journal npj Women’s Health, which indicated that perimenopause symptoms often emerge earlier than previously believed, complicating the already vague timelines that many women receive from healthcare providers. In a separate collaboration with Mayo Clinic, they conducted what both organizations described as the first comprehensive digital study on perimenopause awareness, utilizing data from over 17,000 Flo users across 158 countries.

      The Mayo Clinic research revealed that knowledge about perimenopause varied significantly by region, with higher awareness in the UK, Ireland, and Australia, and lower in Nigeria, France, and parts of Latin America. Nevertheless, the overall trend showed low awareness worldwide. The most frequently reported symptoms were fatigue, mental exhaustion, and irritability, contrasting with the common perception that hot flashes dominate this stage, indicating a mismatch between expectations and experiences that may delay recognition of perimenopause.

      **The business case**

      Flo isn't the first app to focus on perimenopause; for instance, Clue, a Berlin-based cycle tracker, launched a perimenopause mode in 2023. However, Flo's scale offers a unique advantage. The app has been downloaded over 420 million times and became Europe's first femtech unicorn in July 2024 following a $200 million Series C investment from General Atlantic, with gross bookings anticipated to exceed $200 million within the same year. Perimenopause naturally extends their existing user base, as
