Google Health Now Syncs Two Ways With Apple Health on iPhone

Google Health can now share your fitness and wellness data in both directions with Apple Health on iPhone. This makes it easier to use Google’s health tracking tools while staying within Apple’s ecosystem.

The update is rolling out now through the Google Health app on iOS. It allows your health data to flow freely between the two platforms. In the past, the connection between Google Health and Apple Health was limited to one direction. Now, if you log a workout in Google Health, it’ll show up in Apple Health, and the same goes for the other way around.

What Is Two-Way Syncing, Exactly?

Imagine one-way syncing as a street where traffic only moves in one direction. Your data could flow from Apple Health to Google Health, but not the other way. Two-way syncing opens both lanes. Whatever you record in either app—steps, sleep, heart rate, workouts—automatically shows up in the other app.

This is important because many iPhone users find themselves divided between ecosystems. You might wear a Fitbit (which Google now owns) but use an iPhone. That meant your detailed fitness data lived separately from Apple Health. With this update, that barrier is gone.

Why Google Is Opening Up on Apple’s Platform

Google acquired Fitbit in 2021 and has been working to consolidate its health and fitness tracking under a single Google Health umbrella. The Google Health app launched earlier in 2026, combining data from Fitbit devices, Google Pixel Watch, and third-party apps.

Integrating closely with Apple Health is a smart move for Google. Millions of Fitbit users own iPhones. Instead of forcing them to choose between their Fitbit hardware and the Apple Health ecosystem, Google is letting them have both. This makes Google Health more appealing to iPhone users who might not have considered downloading it before.

According to 9to5Mac, the two-way sync covers a wide range of health data categories, not just basic step counts.

What Data Gets Shared

The sync includes core categories you’d expect: steps, active minutes, calories burned, heart rate, sleep data, and workout sessions. When you set it up, you can choose which data types to share in each direction. This gives you control over what moves between the two platforms.

This process is similar to how apps like MyFitnessPal or Strava connect to Apple Health. The key difference is that Google Health now acts as a first-party bridge to Google’s entire health ecosystem, including your Fitbit data, Pixel Watch metrics, and anything logged directly in the Google Health app.

What This Means

For the typical iPhone user with a Fitbit or Pixel Watch, this is genuinely useful. Before this update, your Google and Apple health data existed in separate apps, giving you an incomplete picture. Now, you can check Apple Health and see everything in one place. Alternatively, use Google Health as your main dashboard while keeping Apple Health updated.

This also paves the way for better compatibility with third-party apps. Many iOS health and fitness apps connect to Apple Health as their data source. With Google Health now feeding into Apple Health, those apps will automatically access your Google and Fitbit data without any extra setup required.

If you’re using an iPhone with an Apple Watch, this update might not feel as groundbreaking since the Apple Watch already integrates directly with Apple Health. But for the many iPhone users sporting non-Apple wearables, this update closes a significant gap.

Community Reactions

“Finally. I’ve had a Fitbit for years and hated that none of my data showed up in Apple Health for my other apps to use. This should have existed years ago.”

“Honestly surprised Google did this. Usually these companies want you locked into their own app. Nice to see them playing nice with Apple’s platform.”

How to Set It Up

To enable two-way syncing, update the Google Health app on your iPhone to the latest version. Open the app and go to Settings. You’ll see an option to connect Apple Health. From there, you can choose which data categories sync in each direction. Apple’s standard permissions prompt will appear, allowing you to control what Google Health can read from and write to Apple Health.

As mentioned by 9to5Mac, the feature is rolling out now, so it might take a few days for all users to see it.

What To Watch

• Rollout completion: The feature is currently rolling out gradually. If you don’t see the Apple Health sync option yet, check back in a week or two.
• Data category expansion: The initial sync covers core health metrics. Keep an eye out for Google to add more data types, like nutrition logging or menstrual health data, in future updates.
• Google Health on Android: While this update focuses on iPhone, Google is also actively developing the Android version of the app. The broader Google Health platform is still relatively new, having fully launched in May 2026, so expect more features on both platforms through the rest of the year.
• Apple’s response: Apple has traditionally kept Apple Health data fairly tightly controlled. It’ll be interesting to see if Apple imposes any future restrictions on what third-party apps like Google Health can write back into Apple Health, especially as health data privacy regulations evolve.
