Overview
Flo Health makes Flo, one of the world's most popular apps for tracking menstrual cycles, ovulation, fertility, pregnancy and, increasingly, perimenopause and menopause. Users log periods, symptoms, moods and other health data, and the app predicts cycles, explains patterns and provides medically reviewed health content. A premium subscription adds deeper insights, personalised content and features such as symptom checkers and health assistants. In 2024 Flo became the first purely digital consumer women's health app to reach a valuation above US$1 billion.
Brothers Dmitry Gurski, the CEO, and Yuri Gurski founded Flo in 2015. The company began in Belarus and later moved its headquarters to London, with offices across Europe.
Products
- Period and cycle tracking: logging and predictions based on each user's data.
- Fertility and ovulation: tools for people trying to conceive.
- Pregnancy mode: week-by-week guidance during pregnancy.
- Health insights: symptom tracking, articles and courses reviewed by medical experts.
- Anonymous mode: a feature launched in 2022 that lets users access the app without linking data to their identity.
- Menopause support: expanding content and tools for perimenopause and menopause.
Funding
Flo raised early funding from investors including Target Global and others. In July 2024 it raised more than US$200 million in a Series C led by General Atlantic, a minority investment that pushed its valuation above US$1 billion. At the time, it had nearly 70 million monthly active users and close to 5 million paid subscribers, and said gross bookings in 2024 were projected to exceed US$200 million, up about 50%. It said it would invest in research and development and expand into perimenopause and menopause.
Business model
Flo uses a freemium subscription model: core tracking is free, and premium features require a monthly or annual subscription. Subscription revenue grows with conversion and retention. We show revenue as not disclosed; gross bookings figures are company projections.
Privacy history
Privacy is central to Flo's business. In 2021, Flo settled with the US Federal Trade Commission over allegations that it had shared users' health information with analytics and marketing companies, including Facebook and Google, despite promises to keep it private. Flo agreed to independent privacy reviews and other measures. Related private lawsuits followed in later years. After the US Supreme Court overturned Roe v. Wade in 2022, concerns grew about period data being used in legal cases, and Flo introduced anonymous mode in response. Strong privacy protections are now a central part of its marketing.
Competition
Flo competes with period and fertility apps such as Clue, Natural Cycles, Ovia and Glow, with features built into Apple Health and Fitbit, and with wearable devices that track temperature and cycles. Its advantages are its large user base, content library and brand recognition.

The femtech market
Women's health has historically received less research funding and investment than many other areas of medicine. "Femtech" companies address needs such as menstrual health, fertility, pregnancy, menopause and conditions like endometriosis and polycystic ovary syndrome. Investment has grown but remains a small share of health technology funding. Flo's unicorn status was seen as a milestone for the category, showing that a consumer subscription model can reach scale in women's health.
Who uses Flo
Flo's users include teenagers learning about their cycles, adults tracking health and symptoms, people trying to conceive or avoid pregnancy, pregnant users and those entering perimenopause. Its largest markets include the US, Europe and Latin America.
Menopause: the next growth area
Perimenopause and menopause affect hundreds of millions of women, often with symptoms such as sleep problems, hot flushes and mood changes that are under-diagnosed and under-treated. Digital tools that help women track symptoms, understand what's happening and prepare for conversations with doctors are a growing market. For Flo, expanding into menopause means keeping users engaged across decades of life, not only during their reproductive years.
Risks
- Privacy and trust: any data misuse could seriously damage the brand.
- Platform competition: Apple and other device makers offer free tracking.
- Regulation: health data laws are tightening in many places.
Questions for users
- What data does the app collect, and is it shared with anyone?
- Can you use anonymous mode or delete your data?
- Is health content reviewed by qualified clinicians?
Valuation context
With gross bookings projected above US$200 million in 2024 and a valuation just over US$1 billion, Flo was valued at roughly five times bookings, a modest multiple compared with many consumer subscription apps, reflecting its profitability focus and the privacy risks associated with health data.
Product and research
Flo works with medical experts to review content and has collaborated on research into menstrual health using anonymised, consented data. Research partnerships can improve understanding of women's health, but must meet strict privacy and ethics standards.
Flo's scale also gives it influence in raising awareness of under-discussed conditions such as endometriosis and polycystic ovary syndrome.
Latest developments (October 2026)
Our October 2026 review found no new funding round for Flo Health after its July 2024 Series C of more than US$200 million, led by General Atlantic, which valued it above US$1 billion. At that time the app reported nearly 70 million monthly active users and close to 5 million paying subscribers. Competition from Apple's built-in cycle tracking and other women's health apps remains a key risk. See our consumer health guide.
