Your Fitbit and iPhone are finally ready to compare notes without asking a third-party app to play messenger.
Google Health version 5.05 adds direct Fitbit-to-Apple Health syncing on iPhone, allowing users to send exercise, sleep, steps, vitals, and other wellness data into Apple’s health platform. The update closes a long-standing gap for Fitbit owners who use iPhones and want their activity data available alongside information collected by an Apple Watch or other HealthKit-compatible apps.
Fitbit and Apple Health now work both ways
Until now, the app could read and import information recorded by an iPhone, Apple Watch, and other HealthKit-connected services. However, it could not send Fitbit data back to Apple Health, according to 9to5Mac.
The version 5.05 release notes said users can share exercise records, sleep, vitals, steps, and more from Google Health to Apple Health. Depending on the permissions selected, that information may also become available to other apps that use HealthKit.
The Verge reported that the update removes the need for third-party utilities such as Power Sync for Fitbit or other indirect workarounds. Google Health replaced the Fitbit app in May 2026.
Fitbit devices had never offered native Apple Health syncing, even before Google acquired the company. Fitbit said it had no plans to support HealthKit shortly after Apple introduced the framework in 2014.
How to enable Fitbit and Apple Health syncing
Users can start the connection from Google Health by opening their profile, selecting Partner apps, and choosing Apple Health. Other reports described the route as Connections → Apps and services → Apple Health, so the wording may vary by app interface.
Syncing can also be enabled through Apple Health:
- Open the Sharing tab.
- Select Apps, followed by Google Health.
- Choose the categories of data the apps can exchange.
PhoneArena reported that users may need to restart Google Health and wait before all selected information appears.
Users should review each data category before enabling access. Other HealthKit-compatible apps may also be able to use records shared with Apple Health.
Some Fitbit data may still stay behind
The available sources consistently identify steps, exercise, sleep, heart rate, distance, and vitals as supported data. However, they do not confirm that every metric collected by Fitbit will transfer.
MacRumors cited user reports that heart rate variability, or HRV, does not currently sync. Google has not confirmed the limitation, though differences in how the two platforms calculate HRV may explain it.
For Fitbit users on iPhone, the main benefit is less fragmentation.
Workouts and wellness data can now sit in Apple Health without a separate syncing subscription or workaround. Users should still check that the records they rely on transferred correctly, particularly before using the information in another health app or sharing it with a provider.
