Fitbit is pushing its app closer to a full health companion. Starting next month, you’ll be able to connect your medical records, giving its AI coach access to lab results, prescriptions, and past visits. The same update also improves sleep tracking, with a reported 15 percent boost in detecting sleep stages.
The changes, announced at Google’s Check Up event, show how Fitbit is moving beyond basic activity tracking. By combining clinical records with wearable data, its Gemini-powered assistant aims to deliver guidance that reflects your actual health data. Instead of generic suggestions, you can ask about cholesterol and get answers tied to your real numbers.
What happens when you sleep
Before clinical data integration arrives, users are getting a meaningful upgrade to sleep tracking. Fitbit is rolling out a refined sleep staging model that better separates time spent trying to fall asleep from time actually asleep. Clinical validation shows a 15 percent improvement over the previous version across Pixel and Fitbit devices.
There is also a redesigned Sleep Score that goes deeper into how you rest. It now looks at details like how long it takes you to fall asleep, rather than focusing only on total sleep time. The goal is to help you spot specific habits to improve your routine without guesswork. The updated tracking is available now, while the new scoring experience is expected in the coming weeks for Public Preview users.
Your health data meets AI guidance
The bigger shift arrives next month for Public Preview users in the US. You’ll be able to connect your health records directly inside the app, bringing together information from different providers in one place. Fitbit is working with partners like b. well and CLEAR to support verification, either by searching for your provider or confirming your identity with an ID.

Once connected, the AI coach can interpret that data. Ask about cholesterol, and it can summarize trends, highlight changes, and offer guidance based on both your records and wearable insights. You’ll also be able to share those summaries with a doctor or family member using a QR code or Smart Health Link. Fitbit says this data is stored securely and not used for ads.
Glucose tracking and what’s next
Additional health data is on the way. Around the same time, Public Preview users will be able to connect a continuous glucose monitor through Health Connect. That means you can ask how specific meals or workouts affect your glucose levels, based on your own data.
These updates build on broader research Fitbit is pursuing. A recent study published in Nature explored predicting insulin resistance using wearable signals, and the company is working with Included Health to test how conversational AI can support virtual care. The direction is clear, Fitbit is building a system that understands more about you so its guidance becomes more relevant in daily decisions.
