Google Health 5.05: Fitbit Data Now Syncs to Apple Health 2026
Google Health 5.05 Adds Two-Way Apple Health Sync: Fitbit Data Now Flows to iPhone
Google has released Google Health app version 5.05 for iOS, finally enabling two-way syncing between Fitbit data and Apple Health—a feature that resolves a decade-long gap in cross-platform health tracking. Previously, the Google Health app could only import data from Apple Health, leaving Fitbit users on iPhone unable to send their steps, sleep, workouts, and vitals back to Apple's ecosystem without third-party workarounds. With the August 2026 update, users can now seamlessly share exercise records, sleep data, vitals, steps, and more from Google Health directly into Apple Health, making Fitbit devices significantly more appealing to iPhone users. This article breaks down everything you need to know about the update, how to set it up, what data syncs, and the new Smart Health Links feature for sharing medical records.
Background: From Fitbit App to Google Health
The May 2026 Rebrand
On May 19, 2026, Google officially rebranded the Fitbit app as the Google Health app, marking a major consolidation of the company's fragmented health ecosystem. The update rolled out automatically to existing Fitbit users, transitioning their data and introducing a redesigned interface with four main tabs: Today, Fitness, Sleep, and Health. The rebrand also brought the Google Health Coach—an AI-powered assistant built on Gemini—to the forefront as a premium subscription feature.
However, the initial launch was met with mixed reactions. Users raised concerns about the new AI health coach, interface changes, missing features, and the overall direction of the platform. Google has since addressed many of these complaints through iterative updates, with version 5.05 representing one of the most significant improvements yet.
Google Health vs. Google Fit
It's important to distinguish between the two Google health apps. Google Health (formerly Fitbit) is the consumer-facing app for Fitbit and Pixel Watch users, while Google Fit is a separate, simpler fitness app for general Android users. Google has announced plans to migrate Google Fit users into the Google Health app later in 2026, further consolidating its health offerings.
What's New in Google Health 5.05?
Two-Way Apple Health Sync
The headline feature of version 5.05 is the ability to write Fitbit and Google Health data back to Apple Health. Before this update, the connection was one-way: Google Health could read and import data from Apple HealthKit (such as workouts recorded on an Apple Watch), but it could not export Google Health data back to Apple's platform.
This limitation dated back to 2014, when Apple introduced HealthKit with iOS 8 and Fitbit famously stated it had "no plans to support the platform." For over a decade, iPhone users who preferred Fitbit hardware had to rely on third-party syncing utilities or indirect connections through other services to get their Fitbit data into Apple Health. Version 5.05 eliminates this friction entirely.
What Data Syncs to Apple Health?
According to Google's release notes, the following data types can now be shared from Google Health to Apple Health:
- Exercise records — workouts tracked by Fitbit devices or logged in the Google Health app
- Sleep data — sleep stages, duration, and sleep scores
- Vitals — heart rate, blood oxygen, skin temperature, and other biometric data
- Steps — daily step counts and activity trends
- Additional metrics — cardio load, active zone minutes, and more
Once synced, this data becomes available to other HealthKit-compatible apps on iOS, meaning your Fitbit workouts can now contribute to Apple Fitness+ rings, third-party nutrition apps, or clinical health platforms that read from HealthKit.
How to Enable Apple Health Syncing
Setting up the two-way sync is straightforward:
- Open the Google Health app on your iPhone and ensure it is updated to version 5.05 or later.
- Tap your profile icon in the top-right corner of the app.
- Select "Partner apps" from the menu.
- Choose "Apple Health" from the list of available integrations.
- Follow the on-screen prompts to grant permissions for the data types you want to share.
- Confirm the connection in the Apple Health app when prompted.
Users retain full control over which data types are shared and can revoke access at any time through either the Google Health or Apple Health settings.
Smart Health Links: Share Medical Records Instantly
What Are Smart Health Links?
Beyond Apple Health syncing, Google Health 5.05 also introduces Smart Health Links for users in the United States. This feature allows users to generate a shareable link or QR code containing their medical records, which can be sent to healthcare providers, family members, or caregivers.
Smart Health Links are built on the SMART Health IT framework, an open standard for sharing health information securely. The links are time-limited and can be revoked by the user at any time, providing a balance between convenience and privacy.
How to Create a Smart Health Link
To share your medical records using Smart Health Links:
- Open the Google Health app and navigate to the Health tab.
- Select the "Medical" section.
- Tap "Shareable records."
- Tap the "plus" (+) icon to create a new link.
- Choose which data you want to include in the link (lab results, medications, vitals, conditions, etc.).
- Generate the link and share it via URL or QR code.
The recipient can access the shared records without needing a Google Health account, making it particularly useful for emergency situations or specialist consultations.
US Medical Records Integration
Google Health allows users in the US to sync medical records directly from healthcare providers into the app. This feature pulls data from patient portals and aggregates key information such as lab results, vitals, medications, and visit summaries. The records are securely stored within the app, and users have full control over how the data is used, shared, or deleted.
Google Health Ecosystem: Apps, Devices, and Premium Features
Compatible Devices and Apps
The Google Health app serves as a centralized hub for data from multiple sources:
- Fitbit devices — all current Fitbit trackers and smartwatches
- Pixel Watch — Google's flagship smartwatch
- Google Fitbit Air — a thin, lightweight tracker launched alongside the Google Health rebrand
- Third-party apps — MyFitnessPal, Peloton, and hundreds of others via Health Connect or Google Health APIs
- Apple Health — now with two-way syncing
- Smart scales and accessories — various connected health devices
Google Health Premium and Google Health Coach
Google Health Coach, powered by Gemini AI, provides personalized insights, workout suggestions, sleep analysis, and proactive health recommendations. The coach is available as part of Google Health Premium, a subscription service priced at $9.99 per month or $99 per year.
Premium subscribers also get access to deeper trend analysis, personalized coaching messages, and the ability to ask the coach questions using natural language (such as "Ask Coach" for logging metrics like core body temperature). The free tier of Google Health still provides basic tracking, dashboards, and data aggregation.
Google Health 5.05 vs. Previous Versions: What's Changed?
| Feature | Pre-5.05 | Google Health 5.05 |
|---|---|---|
| Apple Health Sync | One-way only (import from Apple Health) | Two-way sync (export Fitbit data to Apple Health) |
| Smart Health Links | Not available | Available in the US for sharing medical records |
| Data Types to Apple Health | N/A | Exercise, sleep, vitals, steps, cardio load |
| Medical Records Sharing | View only | Shareable via URL/QR code |
| Third-Party Workarounds | Required for Fitbit-to-Apple Health sync | No longer needed |
Why This Update Matters for iPhone Users
Ending the Fitbit-Apple Health Divide
For years, iPhone users who preferred Fitbit hardware faced a frustrating choice: accept that their health data lived in a siloed Google ecosystem, or switch to an Apple Watch for seamless HealthKit integration. Google Health 5.05 removes this compromise. Fitbit users can now enjoy the battery life, sleep tracking accuracy, and form factor of Fitbit devices while ensuring their data contributes to Apple's comprehensive health dashboard.
Improved Workflow for Multi-Device Users
Many users wear an Apple Watch for daily notifications and workouts but use a Fitbit for sleep tracking due to its superior battery life and comfort. With two-way syncing, sleep data from Fitbit can now automatically populate Apple Health, giving users a complete picture of their health without manual data entry or third-party bridges.
Privacy and Data Control
Google has emphasized that Google Health data is not used for Google Ads, a commitment inherited from the Fitbit era. Users can delete their data, export it via Google Takeout, or manage sharing permissions at any time. The Apple Health integration requires explicit user consent for each data type, ensuring that no information is shared without permission.
Known Issues and User Feedback
Despite the positive reception, some users have reported issues with the Google Health app since the May 2026 rebrand:
- Missing Sleep Scores — a long-standing complaint that Google has addressed in recent updates
- UI Adaptation — some users find the new four-tab layout less intuitive than the classic Fitbit interface
- AI Coach Tuning — early feedback suggested the Google Health Coach provided generic advice; Google has been tuning its responses
- 24-Hour Sleep View — added in a recent update to provide a more comprehensive sleep timeline
Google has published a roadmap of 39+ features and fixes rolling out through summer 2026, indicating continued investment in improving the platform.
The Future of Google Health and Cross-Platform Syncing
Google has positioned the Health app as an open ecosystem that works across platforms. In its official announcements, the company stated: "Data portability must be a core tenet for the entire industry." The two-way Apple Health sync is a direct manifestation of this philosophy.
Looking ahead, Google plans to:
- Expand medical records support to more countries beyond the US
- Add support for more data types and deeper third-party integrations
- Improve the Google Health Coach with more personalized, actionable insights
- Migrate remaining Google Fit users into the Google Health app
- Continue refining the app based on user feedback
