Fitbit’s AI-powered health coach is expanding beyond Android and landing on more wrists. Google says the personal health coach, which uses its Gemini model to analyze your activity and wellness data, is now in public preview for Fitbit Premium subscribers on iOS in the US, as well as both iOS and Android users in the UK, Canada, Australia, New Zealand and Singapore.
The updated Fitbit app adds a conversational interface where you can ask the coach questions about your recent workouts, sleep and recovery trends, or long-term goals. The AI can explain what your metrics mean, suggest tweaks to your routine and build custom training plans based on the equipment you have, the time you can commit and the targets you set.
The feature first rolled out in October 2025 in a limited preview, and until now it was only available to Android users in the US. Bringing the coach to iPhone owners and more countries turns it into a more serious competitor to Apple’s own fitness and health services, especially for people who prefer Fitbit trackers or the Pixel Watch over an Apple Watch.
To try the AI coach, you need an active Fitbit Premium subscription, a Google account for sign-in and one of the 14 supported devices, which include recent Fitbit wearables and the Pixel Watch. Fitbit says the rollout will take a few days, so even eligible users might not see the option immediately.
For TB readers, the interesting bit is less the buzzword and more what it means in practice: this is one of the first mainstream, app-level examples of a wearable pairing your data with a large language model in a way you can actually talk to. If it works as advertised, you will be able to ask why your recovery score dipped, whether today is a good day for a hard run or how your new schedule is affecting your sleep — and get an answer that is tailored to your recent history, not a generic blog post.
Of course, it also raises the usual questions about who sees your health data and how those insights are used. Google says the feature follows existing Fitbit privacy controls and that your health data is not used to train general-purpose Gemini models, but if you are wary of sharing detailed workout and sleep logs with big tech, that is something to weigh before switching the coach on.
