Google Adds Medical Records to Fitbit's Gemini Health Coach

Google will let U.S. users link their medical records to Fitbit's personal health coach, an AI assistant built on its Gemini models, the company said on March 17 at The Check Up, its annual health event. In a post on Google's blog, the company said the feature will start next month for Public Preview users in the United States, bringing lab results, medications and visit history into the Fitbit app alongside wearable data.

How records reach the app

Google said it is working with partners including b.well and CLEAR to retrieve records. Users can search for a healthcare provider and link to its patient portal, or verify their identity with CLEAR and have the app search for records on their behalf. The company said it uses IAL2-certified identity standards, requiring a selfie and a valid ID, so that the app can locate and sync records across providers, with availability varying by provider.

The company gave cholesterol as an example of how the coach would use the records: asked how to improve cholesterol, the coach could summarize a user's cholesterol labs, highlight notable values and trends, and give wellness information based on medical history and wearable data. Google said that in the coming months users will be able to share records and summaries with family members or a provider through a Smart Health Link URL or QR code.

On privacy, Google wrote that records are "securely stored with Fitbit" and that users control how their data is used, shared or deleted. "Your medical records, like other health data in Fitbit, is not used for ads," the company said.

The post includes a disclaimer that "Fitbit is not intended to use your medical records to diagnose, treat, cure, prevent, or monitor any disease or condition," and describes the coach as being for general wellness and informational purposes.

Sleep, glucose and research updates

Google also announced what it called its most significant sleep tracking update so far, which it said delivers a further 15% increase in sleep staging accuracy for Public Preview users, measured against clinical gold-standard measurements, along with a redesigned Sleep Score.

Starting next month in Public Preview, users will be able to connect a continuous glucose monitor through Health Connect and ask the coach how activities or meals affect their glucose, the company said. Google also said it will launch a "Get care now" Fitbit Labs research study with Included Health to examine how conversational AI can help people during virtual visits, and pointed to a study on predicting insulin resistance from wearable data that it said was published in Nature that week.

T3 reported that the move places Google in more direct competition with AI-driven health platforms from Apple, Oura, Samsung and Whoop, and that pulling in medical records extends Fitbit's reach well beyond the data it has handled before. The outlet said the feature is rolling out in Public Preview for Fitbit Premium users in select markets.

The Fitbit announcement came days after Microsoft opened a waitlist for Copilot Health, a similar consumer product that links medical records and wearable data to an AI assistant.
