Fitbit’s AI Coach & Your Health Data: Should You Trust Google?

by Priyanka Patel

The fitness tracker landscape is shifting and for many long-time Fitbit users, the changes are prompting a re-evaluation of trust. Google, which acquired Fitbit in 2019 for $2.1 billion, is increasingly integrating its artificial intelligence capabilities – specifically, its Gemini model, rebranded as “Coach” within the Fitbit ecosystem – and requiring users to share their health data to unlock new features. This move, coupled with a recent mandate for Fitbit accounts to migrate to Google accounts, has raised questions about data privacy and control, particularly as the company expands the scope of information it collects to include medical records.

For years, Fitbit stood as a leader in the wearable technology market, known for its accessible fitness tracking and user-friendly app. However, since the Google acquisition, the brand has undergone a transformation. Google discontinued the original Fitbit wearable line in 2024, positioning the Google Pixel as the primary device for Fitbit features. The Fitbit Charge 6 remains available as a dedicated fitness tracker, but the core experience is now deeply intertwined with Google’s broader ecosystem. This integration is most evident in the Fitbit app, where a Premium subscription – priced at $8 per month – unlocks AI-powered insights and personalized guidance.

Google’s AI-Powered Health Coaching and the Push for Medical Data

The introduction of “Coach,” powered by Google’s Gemini AI, represents a significant step in this evolution. Initially trialed on Android devices, the feature has now expanded to iOS users, coinciding with the requirement for all Fitbit users to transition to Google accounts. While Google emphasizes the benefits of AI-driven personalization – claiming that “when your coach understands your medical history, its guidance becomes safer, more relevant and more personalized,” – the move has sparked concerns among users wary of sharing sensitive health information with a tech giant. Google asserts that this data “is not used for ads,” but the reliance on third-party partners to access and process medical records adds another layer of complexity.

The transition to Google accounts wasn’t seamless. The original deadline for switching has been extended to May 19, 2026, acknowledging the frustration and resistance from long-time Fitbit users who preferred the independence of the original platform. This extension, however, does little to alleviate concerns about data privacy, and control.

Partnerships with b.well and Clear: Accessing Your Medical Records

To facilitate the integration of medical records, Fitbit is partnering with two key companies: b.well Connected Health and Clear. B.well is an AI platform designed to aggregate health data from various providers, while Clear is a security platform known for its use in expediting airport security checks. Through Clear, users can search for their medical records using a valid form of identification and a selfie. This process raises questions about the security and privacy of sensitive medical information, and the potential risks associated with sharing such data with third-party companies.

The involvement of these partners highlights the intricate network of data sharing involved in Google’s AI-powered health initiatives. While Google maintains that users have control over their data and how it’s used, the reliance on external platforms introduces potential vulnerabilities and raises questions about accountability.

What Does This Mean for Fitbit Users?

The shift towards AI-driven health coaching and the integration of medical records represent a fundamental change in the Fitbit experience. Users now face a choice: embrace the new features and share their data with Google and its partners, or risk losing access to the full range of Fitbit’s capabilities. This decision is particularly challenging for those who value privacy and are hesitant to entrust their health information to a large technology company.

The move likewise raises broader questions about the future of health data and the role of AI in personalized healthcare. As technology companies increasingly seek to leverage health data for commercial purposes, it’s crucial to establish clear guidelines and regulations to protect user privacy and ensure responsible data handling. The ongoing debate surrounding Fitbit’s integration with Google serves as a cautionary tale, highlighting the importance of transparency, user control, and robust security measures in the rapidly evolving landscape of digital health.

The next step in this evolution will be closely watched as Google continues to refine its AI-powered health features and expand its partnerships. Users can expect further updates and announcements regarding data privacy and security measures in the coming months. For those concerned about these changes, staying informed and actively managing their data settings will be crucial.
