Google to unify Fitbit, Health Connect

Google is moving beyond the older split between Fitbit, Google Fit and Health Connect and into a single health app and data layer. Il Sole 24 Ore reported on May 17 that the company is working to unify Fitbit, Health Connect and Google Health as part of a broader health platform. Google has not publicly described that effort in the same terms, but its own product materials now point in the same direction: one app, one data view and wider ingestion of health information. The immediate change is visible in Google’s product branding. Google said last week that the Fitbit app is “entering a new era” as the Google Health app, and that existing Fitbit users will be upgraded automatically while Google Fit users begin migrating later in 2026. That makes the story less about a single new wearable and more about how Google wants health data to move through its software stack. ### What exactly is Google combining? Google’s own support and product pages show three layers that had been separate. Fitbit has been the consumer-facing app and wearable brand; Health Connect has been Android’s on-device permissions and data-sharing hub for health apps; and Google Fit has remained the older Google-branded fitness service for many users. Google said in a blog post last week that the new Google Health app will bring together data from wearable devices, Health Connect, Apple Health and medical records into one place. Fitbit’s help pages separately say Android users can already add Health Connect to the Fitbit app to view data from connected apps and devices inside Fitbit. That means the consolidation is not only a rename. It is also a change in where users see their health information and how Google presents data that may originate from multiple sources. ### Where does the Il Sole 24 Ore report go further? Il Sole 24 Ore said on May 17 that Google is building toward a broader “body operating system” centered on Gemini and continuous health data. The report said the plan would unify Fitbit, Health Connect and Google Health and could expand compatibility over time to devices from Garmin and Whoop. Google has publicly confirmed the app consolidation pieces, but not the full roadmap described by Il Sole 24 Ore. The newspaper’s article frames the project as an AI-led system that watches signals such as sleep, recovery, nutrition and activity and then offers suggestions. That language matters because Google’s official announcement already points to a wider data model than Fitbit alone. The company said the app will combine information from multiple health sources and will soon let users share data securely with friends, family and doctors. ### Could Garmin and Whoop data realistically plug in? Garmin and Whoop already operate developer platforms that expose health and wearable data to outside applications. Garmin says its Health API provides metrics including steps, heart rate, sleep and stress, while Whoop says its developer platform lets partners build integrations around member data. Those existing APIs do not prove a Google deal. They do show that the technical path for cross-vendor ingestion already exists if commercial agreements and user permissions are put in place. Google’s own announcement also leaves room for outside-device data. The company said the Google Health app will ingest information from “wearable devices,” without limiting that phrase to Fitbit hardware in the product description surfaced last week. ### What happens to Fitbit and Google Fit users now? Google said existing Fitbit users will automatically be upgraded to the Google Health app. The company also said Google Fit users will begin migrating into Google Health later this year. Fitbit help pages now describe features under the redesigned Google Health app, including medical-record management and Health Connect setup on Android. That signals that Google is shifting user support, branding and feature development toward the new app rather than maintaining separate consumer destinations. ### Where does AI fit into the product? Il Sole 24 Ore tied the strategy to Gemini, Google’s flagship AI model family, and described a system that could turn health signals into recommendations on recovery, sleep and nutrition. Google’s blog post did not use the “body operating system” phrase, but it did pair the new app with broader health features and data sharing. Last week’s Google materials also introduced a new Fitbit Air device and referenced Google Health Premium, suggesting the company is packaging hardware, software and subscription services more tightly around the health app. Later this year is the next concrete milestone. Google said that is when migration of Google Fit users into the Google Health app will begin, while the company’s newly branded app is already positioned as the main destination for Fitbit users and connected health data.
