Google Health 5.05 now lets iPhone users send supported Fitbit-recorded data into Apple Health, closing a one-way sync gap that has frustrated mixed-device users for years. The change matters most for people who wear a Fitbit but treat Apple Health as their main health record on iOS.
The update adds two-way Apple Health syncing for workouts, steps, sleep and other supported metrics, according to Notebookcheck. It also brings Smart Health Links to US users, allowing stored medical records in Google Health to be shared with providers or family members by URL or QR code.
Google Health gives iPhone-based Fitbit users the missing Apple Health write path
Until this release, Google Health on iPhone could pull data from Apple Health, HealthKit and Apple Watch, but it could not send Fitbit-collected data back into Apple’s health app without third-party utilities or other workarounds.
Version 5.05 changes that. Fitbit workouts, steps, sleep information and other supported categories can now move from Google Health into Apple Health, subject to the permissions selected by the user.
“Share your data like your exercise records, sleep, vitals, steps, and more from Google Health to Apple Health.”
That release-note language was cited by 9to5Mac, which reported that the update adds the missing “write” side of the connection.
The gap stretches back to 2014, when Fitbit declined to support Apple’s newly launched HealthKit platform. That history matters because this is not a minor toggle. It removes a structural separation between two major consumer health data systems.
| Google Health on iPhone | Before version 5.05 | After version 5.05 |
|---|---|---|
| Read Apple Health data | Yes | Yes |
| Import Apple Watch / HealthKit data | Yes | Yes |
| Write supported Fitbit data to Apple Health | No | Yes |
| Share Google Health medical records by link or QR code in the US | Not cited in supplied source | Yes |
Can a Fitbit user now treat Apple Health as the main hub and ignore Google Health entirely? Not quite. The transfer applies only to supported metrics, and early reports say heart rate variability does not carry over yet.
Fitbit users on iOS get a cleaner health data hub inside Apple Health
For iPhone owners who mix devices, the practical win is simple: a Fitbit can now feed Apple Health more directly. That makes daily activity, sleep trends and workout history easier to keep in one place.
The new option appears in the Partner apps section of the Google Health app, where users can link Apple Health and choose permissions. Those controls matter because Apple Health access is category-by-category, not an all-or-nothing switch.
What should users check first after updating? The categories Apple Health says Google Health can read and write.
Supported data named in the supplied sources includes:
- Workouts: Fitbit-recorded exercise records can sync into Apple Health.
- Steps: Daily step counts can move from Google Health to Apple Health.
- Sleep: Sleep information is included among supported metrics.
- Vitals: 9to5Mac cites “vitals” in Google’s release-note language.
- Other supported metrics: Google has not published a complete category list in the supplied material.
The biggest caveat is HRV. Notebookcheck says metrics such as heart rate variability reportedly do not transfer yet. Android Authority also cited Reddit commenters who said HRV was not moving from Google Health to Apple Health, with one user suggesting the issue may relate to differences in how the two platforms calculate the metric.
That explanation is not confirmed by Google in the supplied sources. For serious fitness users, HRV may still require opening Google Health.
This is a different type of iPhone platform story from MLXIO’s coverage of Apple’s services and device strategy, including Apple Upgrade Turns iPhones, Macs and iPads Into Leases and Liquid Glass Finally Hits WhatsApp Mac—But Only for Some. Here, the issue is not Apple adding a feature. It is Google making Fitbit data more usable inside Apple’s health system.
US patients can share Google Health medical records by link or QR code
The second major change in Google Health 5.05 is Smart Health Links for US users. The feature lets people share medical records stored in Google Health with healthcare providers, family members or other trusted recipients.
Notebookcheck says those records can be shared through a URL or QR code. Android Authority reports the feature is available on both Android and iOS in version 5.05.
Why does that matter beyond fitness tracking? Because it pushes Google Health deeper into personal health record management, not just wearable data.
A patient coordinating care could use a Smart Health Link to share stored records with a doctor or family member. The supplied sources do not specify which medical record types are supported, so users should not assume every lab result, visit summary or document will be available through the feature.
The core idea is still clear. Google is adding a sharing layer for stored medical records while also loosening the wall between Fitbit data and Apple Health.
That combination makes version 5.05 more than a Fitbit convenience update. It gives Google Health two jobs at once: sync wearable data across platforms and move selected medical records to people who need access.
Permissions, missing metrics and real-world access now decide the rollout’s value
The immediate user questions are practical. Which categories appear after updating? Does a specific Fitbit model expose all expected data? How does Apple Health handle overlapping records when both Apple Watch and Fitbit log similar activity?
The supplied sources do not answer those questions in full. They confirm the broad write path from Google Health to Apple Health, named categories such as exercise, sleep, vitals and steps, and the reported HRV gap.
Privacy and consent sit at the center of both features. Fitness, sleep and medical records are sensitive data, and Google Health’s new value depends on users understanding exactly which permissions they grant.
The Smart Health Links rollout has a separate test: whether providers and family members can access shared records easily in real care situations. A URL or QR code reduces friction, but the supplied material does not say how recipients view, verify or import those records.
The next thing to watch is Google’s documentation. Gadgets & Wearables reported that Google’s existing support page still said the app could not write data to Apple Health and that the capability would arrive later in 2026, even as version 5.05 began rolling out. If the app is ahead of the docs, users should expect some confusion until Google clarifies supported metrics, setup paths and limits.
What This Means For You
- iPhone users who wear Fitbit devices can now keep Apple Health as a more complete central health record.
- The update removes a long-standing sync gap between Fitbit data and Apple’s HealthKit ecosystem.
- Smart Health Links add a new way for US users to share stored medical records with providers or family members.
