When does the Google Health and Flo integration start?

Google says users can sync Flo with Google Health starting in early 2027. A specific date has not been announced.

Do I need a subscription to use it?

Syncing the apps is described as opt-in. Feeding Flo data into the Google Health Coach requires a Google Health Premium subscription, sold separately.

Which wearables will work?

Google names the Fitbit Air, Fitbit Edge and Pixel Watch 5 as examples. Some features are limited to select devices.

Will Google sell or use my Flo data for ads?

According to Google, no. Shared Flo data will not be used for advertising, will not be sold, and will not be available to other apps or developers through Google's health platforms.

Can I choose what to share?

Yes. Permission is asked separately for each data type and purpose, and it can be withdrawn at any time.

Can I use it as birth control or to get pregnant?

No. Google states the cycle feature provides general wellness estimates only. It is not for contraception, conception or other medical use.

PMOS stands for polyendocrine metabolic ovarian syndrome. It is one of the conditions named in the planned research.

Are new Google and Flo products coming?

Both companies say they plan to build women's health products together. No products have been named yet.

Google Health + Flo Integration 2027: What We Know So Far

Two big names in health tech just joined forces.

On October 12, 2026, Google Health announced a multi-year partnership with Flo, the cycle tracking app used by more than 80 million people every month. Google also made a strategic investment in the company.

The first big change lands in early 2027. Here is what is confirmed, and what is not.

The short version

Flo will be able to sync with Google Health from early 2027.
Syncing is opt-in. Nothing moves without your permission.
Cycle data can be combined with wearable data like sleep, heart rate and skin temperature.
Flo data can feed the Google Health Coach, but that needs a Google Health Premium subscription.
Research and new women's health products are planned. None are named yet.

What the partnership includes

Google describes four parts to the deal.

1. App syncing

From early 2027, users can link Flo with Google Health. Cycle data can sit next to resting heart rate, heart rate variability, skin temperature and sleep stages. Data can also flow the other way, from Google Health into Flo. The goal is simple: your cycle and your body signals in one picture, instead of two apps that never talk.

2. Google Health Coach

Flo data will plug into the Google Health Coach. The Coach can then link cycle, sleep and recovery to give guidance, including support around perimenopause. This part needs a Google Health Premium subscription, which is sold separately.

3. Research

The two companies plan joint research. Topics named include perimenopause, PMOS (polyendocrine metabolic ovarian syndrome), pregnancy and postpartum recovery. Some reports also mention an AI model that studies how hormones affect health, with possible links to conditions like endometriosis and fibroids. No projects or dates have been shared.

4. New products

Google and Flo say they will build products designed for women, combining Flo's health insights and algorithms with Google's wearable hardware and sensors. Nothing has been named or dated.

Which devices are involved

Google points to three wearables as the examples:

Fitbit Air
Fitbit Edge
Pixel Watch 5

These are 24/7 wearables. That matters because cycle insights lean on overnight data like temperature and sleep. Some features will only work on select devices. The Fitbit Edge also lets users log cycle dates and symptoms, and see period predictions and cycle phases, right on the wrist or in the Google Health app.

How privacy works

Health data is personal. Google and Flo say the setup is strictly opt-in.

Permission is requested separately for each type of data and each purpose.
It can be withdrawn at any time.
Flo data shared with Google Health will not be used for advertising.
It will not be sold.
It will not be made available to other apps or developers through Google's health platforms.

Flo's CEO has called the approach "privacy-first." Technical details have not been published yet.

A note on accuracy

The cycle features give estimates for general wellness. Google is clear that they should not be used for contraception, trying to conceive or any medical purpose. Coach answers can also be wrong. For health concerns, a doctor is the right call.

What this means for you

If you already use Flo and wear a Fitbit or Pixel Watch, the integration could make your data work harder. Sleep and recovery trends sitting next to cycle phases can help spot patterns.

If you do not use either, there is nothing to do yet. The sync is still months away. This page will be updated as soon as the sync goes live.
