We’re adding medical records, advanced sleep science and metabolic research to give you more tools on the path to live a longer, healthier life.

Basic explainer

Fitbit is making its health tracking even better with AI. The new AI coach will give you more personalized advice about your sleep and health. You can even connect your medical records to the Fitbit app. This helps the AI coach give you better, safer, and more useful advice.

Last year, we introduced the vision of a personal health coach ¹ built with Gemini to move beyond basic metrics and provide truly personalized guidance. Today at The Check Up, our annual health event, we’re taking the next step. We’re introducing significant updates to help you understand and improve your sleep, sharing how we’re advancing health through new research, and integrating clinical history to provide a more comprehensive view of your well-being.

New updates from Fitbit across sleep, advanced research and securely linking your medical records.

Improving sleep accuracy and insights

We’re launching our most significant update yet, delivering an additional 15% increase in sleep staging accuracy for Public Preview users. ²

Trained on diverse, inclusive datasets, our models now better distinguish between when you are aiming to sleep and when you are asleep. These improvements more accurately capture interruptions, naps and transitions between stages, aligning with clinical gold-standard measurements.

This rigorous foundation powers a reimagined, transparent Sleep Score designed to make your data more actionable. The new score evaluates specific aspects of your rest — not only how much sound sleep you got, but how long it took you to get there. This level of detail provides targeted coaching, helping you understand exactly where to focus your routine for better recovery.

This enhanced tracking rolls out over the next few days, with the new Score experience following in the coming weeks for Public Preview users.

Advancing health through research

A great health coach supports you holistically across your health and wellness. That’s why we’re investing deeply in advanced health research to expand the insights and experiences the coach can support. This week, our pioneering study on predicting insulin resistance using wearable data was published in Nature. This foundational work, alongside our ongoing Fitbit hypertension study, lets us invest in AI that better understands your cardiometabolic health and potentially enables early awareness — allowing you to take proactive actions and the coach to help you make lifestyle adjustments.

We also want to make these insights even more actionable. In the next couple of weeks, we’re launching a new “Get care now” Fitbit Lab research study in partnership with Included Health, a leading U.S. healthcare provider to assess how conversational AI can help you navigate your health during virtual visits. Separately, starting next month in Public Preview, you'll be able to connect a continuous glucose monitor (CGM) through Health Connect and ask your coach how a specific workout or even that slice of pizza actually impacts your glucose levels.

Getting a fuller picture of your health

Starting next month for Public Preview users in the U.S., you'll be able to link your medical records to the Fitbit app for a fuller picture of your health including your lab results, medications and visit history, all in one place and under your control.

To make this possible, we’re collaborating with partners like b. well and CLEAR. You can search for your healthcare provider and then link to their portal, or simply verify your identity with CLEAR and we will search for records on your behalf. By using IAL2-certified standards — requiring only a selfie and a valid ID — this enhanced security allows the app to automatically locate and sync your records across different providers (availability varies per provider).

When your coach understands your medical history, its guidance becomes safer, more relevant and more personalized. For example, instead of getting a generic answer about cholesterol, you can ask, “How can I improve my cholesterol?” The coach can then summarize your cholesterol labs, highlighting notable values and trends, and provide personalized wellness information based on your medical history and wearable data. In the coming months, you'll be able to securely share your records and these summaries with your family or provider, using a Smart Health Link URL or QR code.

Of course, data privacy is key when it comes to medical records, or any personal health data. Your records are securely stored with Fitbit, and you have control of your data and how it's used, shared or deleted. Your medical records, like other health data in Fitbit, is not used for ads. You can learn more in our public commitments found in our Fitbit privacy policy.
