Fitbit’s AI-powered health coach is now available to iPhone users in the US and to both iOS and Android users in several other countries, marking a significant expansion of the service.
The personal health coach, which utilizes Google’s Gemini model to analyze activity and wellness data, is available in public preview for Fitbit Premium subscribers on iOS in the US, as well as on both iOS and Android in the UK, Canada, Australia, New Zealand, and Singapore. The updated Fitbit app features a conversational interface, allowing users to ask the coach questions about their recent workouts, sleep and recovery trends, or long-term goals. The AI can explain the meaning of various metrics, suggest adjustments to a user’s routine, and create custom training plans based on the equipment available, the time that can be committed, and the targets set.
The feature initially rolled out in October 2025 in a limited preview and was previously only available to Android users in the US. By bringing the coach to iPhone owners and expanding its availability to more countries, Fitbit is making the service a more serious competitor to Apple’s fitness and health services, particularly for individuals who prefer Fitbit trackers or the Pixel Watch over an Apple Watch.
To access the AI coach, users require 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 notes that the rollout will take a few days, so eligible users may not immediately see the option.
The integration of a large language model with wearable data represents one of the first mainstream examples of its kind at the app level, enabling users to engage in a conversational manner with their health data. If the service works as advertised, users will be able to inquire about specific aspects of their health and fitness, such as the reasons behind a dip in their recovery score or the suitability of a particular day for a hard run, and receive tailored responses based on their recent history.
However, the introduction of this feature also raises concerns regarding who has access to health data and how those insights are utilized. Google states that the feature adheres to existing Fitbit privacy controls and that user health data is not used to train general-purpose Gemini models. Nonetheless, individuals wary of sharing detailed workout and sleep logs with major technology companies may want to weigh these considerations before activating the coach.
