Google Enhances Fitbit's Personal Health Coach with New Features

In October 2025, Google introduced its AI-powered personal health coach, Coach, for Fitbit Premium subscribers, initially available on Android. Following a successful preview, the service expanded in February 2026 to include iOS users and Fitbit Premium members in Canada, the UK, Australia, New Zealand, and Singapore. At the annual The Check Up health event, Google announced significant updates to Coach, focusing on sleep tracking, medical records integration, and continuous glucose monitoring.

One of the most notable updates to Fitbit's Coach is the enhancement in sleep tracking, which now boasts a 15% increase in sleep stage accuracy. The updated algorithm can differentiate between attempts to sleep and actual sleep, as well as identify napping and sleep interruptions. This improved functionality will contribute to a revamped Sleep Score, which will evaluate not only the duration of sleep but also the time taken to fall asleep, allowing for more personalized insights and recommendations for better sleep.

Starting in April 2026, US subscribers will have the ability to link their medical records—such as medications, lab results, and doctor visit history—within the Fitbit app. This feature, developed in collaboration with B. Well Connected Health and Clear, enables users to search for their healthcare providers and access their medical information securely. Once identity verification is completed, Coach can utilize this medical history to offer tailored health guidance based on the user's comprehensive health data.

Despite the advancements, privacy concerns remain prevalent. Experts advise caution when uploading sensitive medical information to AI platforms. Fitbit assures users that their medical records will be securely stored and that individuals maintain control over their data, including sharing and deletion options. The company emphasizes that medical records will not be used for advertising purposes. However, it is important to note that AI health coaches are not substitutes for professional medical advice, and users should consult their healthcare providers before making any health-related changes.

Google's commitment to health research is evident as it explores topics such as predicting insulin resistance and hypertension using wearable data. Additionally, in April 2026, Fitbit members will be able to connect continuous glucose monitors to the app via Health Connect, allowing users to analyze how their dietary choices and physical activities impact glucose levels.
