Google has begun rolling out an update to the Google Health app for iOS that allows Fitbit data to sync directly with Apple Health, closing a gap that has existed between the two platforms since Apple Health launched in 2014.
As first reported by 9to5Mac and confirmed by The Verge, version 5.05 of Google Health enables two-way sharing between the apps. Users can now send exercise records, sleep data, vitals, steps, and other metrics from Google Health to Apple Health. Until this update, the connection worked only in the opposite direction: Google Health could read and import data from Apple Health, but could not write Fitbit data back.
To set up the sync, users can open the Google Health app, tap their profile icon, select “Partner apps,” and choose Apple Health, according to the update’s release notes. Permissions for individual data categories can be managed from either app.
Fitbit devices have never offered native support for Apple Health. Shortly after Apple introduced HealthKit with iOS 8 in 2014, Fitbit said it had no plans to integrate with the platform. iPhone users who wanted Fitbit data in Apple Health typically had to rely on third-party utilities such as Power Sync for Fitbit or Fitbit to Apple Health Sync, often paid apps that acted as bridges between the services.
Google Health replaced the Fitbit app in May 2026. The transition brought a redesigned interface with four main tabs,Today, Fitness, Sleep, and Health,along with new features including an AI health coach. The rollout drew user complaints about the interface and the AI coach, though Google has since addressed some of those concerns through subsequent updates.
Alongside the Apple Health sync, version 5.05 introduces Smart Health Links for users in the United States. The feature lets users generate shareable links for medical records that can be sent to healthcare providers or family members via URL or QR code.
Early testing indicates the integration does not transfer every data type. MacRumors noted that heart rate variability does not currently appear to sync, and proprietary Google metrics such as Cardio Load and Readiness are unlikely to transfer because Apple Health lacks direct equivalents for those scores. Some users have also reported inconsistent historical data syncing during the initial rollout.
Google Health 5.05 is available now as a free update on the App Store.
