TL;DRFlo Health, the world’s largest women’s health app with 80 million monthly active users, is launching a new suite of perimenopause tools for premium subscribers in May 2026. A Wakefield Research survey found 66% of US women aged 38-50 felt better prepared for puberty than perimenopause. The tools include a Symptom Checker, Perimenopause Score, Menopause Timeline, and Relief Options. Flo’s research with Mayo Clinic and a Nature-published study underpin the clinical approach. The company became Europe’s first femtech unicorn in 2024 after a $200M Series C from General Atlantic.
Two-thirds of American women between 38 and 50 say they felt better prepared to go through puberty than perimenopause. The statistic, from a nationally representative survey commissioned by Flo Health and conducted by Wakefield Research, captures something that decades of public health messaging have failed to fix: most women arrive at one of the most disruptive hormonal transitions of their lives with less reliable information than they had as teenagers.
Flo Health, the period-tracking app that has grown into the largest women’s health platform in the world with 80 million monthly active users, is attempting to close that gap with a new suite of perimenopause tools launching this month for its premium subscribers. The features, a symptom checker, a perimenopause severity score, a menopause timeline tracker, and a medically verified relief-options guide, represent the company’s most significant product expansion since it achieved unicorn status in 2024.
