Google has quietly released a major update to its Health app on iOS that allows Fitbit users to synchronize their fitness and health data directly with Apple Health, ending years of frustration for users who switched between the two ecosystems.
The Google Health 5.05 update, which began rolling out on Monday, introduces bidirectional syncing between Fitbit’s data platform and Apple HealthKit. This means Fitbit users can now view their steps, heart rate, sleep data, and workout history inside the native Apple Health app, and Apple Health-compatible apps can pull from Fitbit’s sensor data.
For years, Fitbit and Apple Health existed as largely separate silos. Fitbit kept its data within its own app and web dashboard, while Apple Health relied on third-party apps and manually entered information. Users who owned Fitbit trackers but used iPhones were forced to choose between seeing their data in Fitbit’s app or Apple’s, but rarely both.
The move is significant because Google acquired Fitbit in 2021 for $2.1 billion and has been gradually integrating the brand into its broader health strategy. By opening Fitbit’s data pipeline to Apple Health, Google appears to be prioritizing reach and user retention over keeping users locked into its own ecosystem.
The sync covers a wide range of health metrics including daily step counts, active zone minutes, heart rate trends, SpO2 readings, skin temperature variations, and detailed sleep stage breakdowns. Workout data from Fitbit devices also transfers over, including GPS routes for outdoor activities and calorie burn estimates.
Analysts noted that the update could help Google compete more effectively with Apple Watch, which has long benefited from deep integration with Apple Health. By making Fitbit data available in Apple’s health infrastructure, Google may be betting that open interoperability will attract users who value flexibility over ecosystem loyalty.
The update is available now on the App Store for iPhone users with a Fitbit account. Google said the feature will expand to additional platforms in the coming months, though no specific timeline was provided for Android integration changes.
