Monitoring your health is easier than ever thanks to wrist and finger wear Fitness trackers. But analysis of the collected data is largely left to the user. Until recent years, when some of the technology companies that make these wearable devices launched their own products AI health coaches.
In October 2025, Google debuted its version called Coach, powered by Gemini AI, to US Fitbit Premium subscribers on Android. However, the launch in October was just a preview, as the company sought feedback from early users. In February of this year, Google expanded the Coach’s public preview To include iOS users and Fitbit Premium members in Canada, the United Kingdom, Australia, New Zealand, and Singapore. Google announced Tuesday at its annual The Check Up Health event that it is adding additional features to its all-in-one fitness coach, sleep coach and health advisor.
A Google representative did not immediately respond to a request for comment.
Improve sleep insights and recording
As for sleep tracking, the company’s most significant update yet delivers a 15% increase in sleep stage accuracy, based on comparisons of previous state-of-the-art algorithms across compatible Pixel and Fitbit devices.
The current model will also now be better able to differentiate between when you are trying to sleep and when you are actually asleep. It can detect when you’re taking a nap, when your sleep is interrupted, or when you’re transitioning between sleep stages.
Within a few weeks, all of these improvements will contribute to an improved Sleep Score that will focus not only on the amount of sleep you got, but on the amount of time it took you to get that sleep. Because it has more sleep data to work with, Coach will be able to provide more informed insights and recommendations for better sleep.
Fitbit’s upcoming personal health coach updates center around sleep, medical records, and continuous glucose monitoring data.
Availability of medical record
In April, subscribers in the United States will be able to link their medical records, such as medications, lab results and doctor’s visit history, to the Fitbit app.
This feature was created in collaboration with B. Well Connected Health, an AI-powered digital health platform that aggregates health data from different providers, and Clear, an identity verification platform known for airport security.
In the Fitbit app, you can search for your doctor and then link to their member portal. Or if you use Clear to verify your identity with a photo and a valid ID, it will search your medical records for you. Availability depends on your service provider.
Once your identity is verified, your Fitbit Personal Health Coach can access your medical records.
Your Fitbit Coach can then use your medical history to create more personalized instructions that combine your lab results, data collected by Fitbit, and any other relevant information it collects from your records. Within several months, users will be able to share these records and summaries with their provider or family members using a QR code or Smart Health Link URL.

Privacy is always a concern
Privacy experts are warning people To think twice before uploading medical information to an AI tool.
Fitbit says It stores your medical records securely, and you can control how your data is used, whether it is shared, and whether it is deleted. The company also says your medical records will not be used for ads.
AI-based health coaches are not a substitute for a doctor, as they cannot diagnose or treat medical conditions. You should not make any changes to your lifestyle or health routine without consulting your doctor.
The future of the personal health coach at Fitbit
Google also announced that it is investing in health research on topics such as Prediction of insulin resistance Using data collected by wearable devices, High blood pressure And learn more about it How AI performs in virtual care settings. These study topics help us learn what Google might have in store for future Fitbit updates.
In April, Fitbit members in public preview will also be able to connect their continuous glucose monitor to the Fitbit app via Health Connect. This feature allows you to see all your health data from compatible apps in one place. Through this link, Fitbit members can ask their coach for more information about how exercise or meal choices affect their glucose levels.
