Google’s conversational health assistant rolls out to the UK, Canada, and Australia
Google is significantly expanding the reach of Fitbit Coach, its Gemini-powered personal health assistant, by bringing the feature to iOS users and five new international markets.
Previously limited to Android users in the US after its October rollout, the public preview is now available to Fitbit Premium subscribers in the UK, Canada, Australia, New Zealand, and Singapore.
The update, which is expected to reach all eligible users over the next few weeks, allows Fitbit tracker owners with an iPhone to finally test the conversational AI that Google is positioning as the centerpiece of its long-term health strategy.
How Fitbit Coach works
Fitbit Coach is designed to move the platform beyond static charts, acting as a real-time health advisor that interprets a user’s physiological data. During a 5- to 10-minute onboarding chat, users share details about their fitness goals, current injuries, and available gym equipment.
The AI then uses this context, along with historical wearable data, to build dynamic training plans. For example, if the system detects poor sleep or a low readiness score, it can automatically suggest a lower-intensity recovery session instead of a planned high-intensity cardio workout.
The expansion coincides with a major redesign of the Fitbit app interface, which now features four core tabs: Today, Fitness, Sleep, and Health. A new ‘Ask Coach’ floating button is accessible throughout the app, allowing users to ask natural-language questions such as “How did my weekend run affect my recovery?” or “Can you build a marathon plan based on my current pace?”

The system even analyzes long-term trends, comparing a user’s sleep quality to similar demographic groups and explaining how specific lifestyle factors—like late-night cardio load—are impacting their rest.
Who can join the Fitbit Coach preview
To join the preview, users must have an active Premium subscription and a modern Fitbit or Pixel Watch, including the recently released Pixel Watch 4.
While still in the ‘Public Preview’ stage, the expansion suggests Google is confident enough in the Gemini model’s accuracy to begin a global rollout, directly challenging Apple’s rumored pivot toward a more premium, AI-powered health presence coming later this year.
