Google Invests in Flo Health and Prepares Wearables for Women's Health

Google has taken an equity stake in Flo Health, the developer of the Flo menstrual cycle tracking app. The companies announced the deal on Monday, October 12, 2026. The partnership is multiyear, and neither side disclosed the size of the investment. There is only one concrete detail: from early 2027, users will be able to link Flo to the Google Health app, and women's health data will become part of Google's wearables and coaching.

What we know about the deal

Public details are scarce. According to Engadget, the integration will go live in early 2027. Metrics collected by Fitbit devices will be able to be compared with data from Flo. The list of metrics is cut off in the original report, so the full set is still unclear. Heart rate, sleep and skin temperature would be logical to expect, but nothing has been confirmed.

Key facts:

• Investor: Google, a minority stake in Flo Health (the exact size is not given).
• Format: a multiyear partnership, not a one-time acquisition.
• Sync launch timing: early 2027.
• Platform: the Google Health app and Google wearables.
• Plans: a separate line of wearable gadgets for women's health.

Why Google wants this

Google has a hardware base: it bought Fitbit in 2021, and wearables have remained a weak spot for the company ever since, next to the Apple Watch and Oura. Women's health offers a way to stand out in this niche. Cycles, ovulation, pregnancy and menopause generate a steady stream of data that in itself keeps a person in the app. Watches with sensors become more useful when there is a service with an already accumulated history of observations.

The second reason is coaching. Personalized recommendations rely on context, and the menstrual cycle strongly affects sleep, recovery and training load. Generic advice like "get more sleep" is noticeably weaker than tips that account for the cycle phase. The companies did not say what exactly Google will build into the coach or which models will power it.

For Flo, the deal means access to distribution and hardware data without having to manufacture its own devices. The app has long had hundreds of millions of installs, but it has no hardware.

Risks that will have to be discussed

Menstrual cycle data falls into the most sensitive category of personal information. Since the US overturned Roe v. Wade in 2022, the question of who can access such records has stopped being abstract. Flo itself has a history here: in 2021 it settled claims by the US Federal Trade Commission over sharing user data with third-party services. Google, for its part, regularly faces questions about mixing data across different products.

It is still unknown on what terms data will be passed between Flo and Google, whether it can be used for advertising, and how consent will work. Trust depends on the answers to these questions, and without trust the integration will not take off.

What users and the market should do

Before the 2027 launch, Flo and Fitbit users would be wise to check the privacy settings in both apps in advance. Once syncing becomes available, it makes sense to enable it deliberately and by individual data category, if such an option appears. Watch whether data sharing for ad personalization is permitted.

Competitors such as Apple, Oura and Samsung will have to respond with partnerships of their own or by deepening their own cycle features. For those building digital health products, the deal shows the direction: value has shifted from the tracker itself to the combination of service plus sensors plus personal coach. The size of the stake and the details of the integration should become clearer closer to launch.
