If you use Fitbit and have been waiting to see what its new AI coach can really do, you’re in luck. Google is expanding Fitbit’s Gemini-powered personal health coach to more countries and, for the first time, to iPhone users.
The Public Preview, which first launched in the US on Android last October, is now rolling out to iOS users in the US and to both iOS and Android users in the UK, Canada, Australia, New Zealand, and Singapore. The feature remains tied to Fitbit Premium and supported devices, reinforcing Google’s strategy of pairing generative AI with subscription-based health services.
Public preview reaches iOS and new countries
Google said in a blog post that Fitbit’s personal health coach is “expanding to more people around the world.” The company noted that the rollout will begin immediately and continue over the next few weeks for eligible Premium users in the new markets. Users will receive updates and fixes directly within the Fitbit app.
The Verge reported that iPhone users in the US can now access the AI feature, while users in the UK, Canada, Australia, New Zealand, and Singapore can join on both iOS and Android. The preview first launched in October and was limited to Android users in the US.
To participate, users must have an active Fitbit Premium subscription, sign in with a Google account, and use one of 14 supported devices, including Fitbit wearables and the Pixel Watch. According to Fitbit, the feature will roll out “over the next few days,” so not all eligible users will see it immediately.
9to5Google also emphasized that the preview remains optional and that users can switch between the redesigned app and the legacy interface during testing.
Gemini powers a redesigned Fitbit experience
The update marks a significant redesign of the Fitbit app. At its core is a conversational interface powered by Google’s Gemini models. The AI interprets recent health metrics, generates custom workout routines, and responds to questions tailored to a user’s goals and available equipment.
On its Made by Google YouTube channel, Google emphasized that the Fitbit app is completely redesigned and is built to be your fitness trainer, sleep coach, and health and wellness advisor. “Things are actively shifting as we build this experience with you. That’s why your feedback is essential,” the company said.
According to Android Central, the onboarding process begins with a short chat about fitness objectives, sleep habits, and training preferences. From there, the Today and Fitness tabs present structured plans with suggested workouts and target metrics that adjust in real time. Dedicated Sleep and Health tabs generate and identify trends across metrics such as heart rate variability, breathing rate, blood oxygen levels, and skin temperature variation.
Android Central’s Derrek Lee, who tested the feature, wrote, “Despite its shortcomings, I think Google is on the right track with this new Fitbit experience.” He described the setup as detailed but said the tool could appeal to users seeking deeper insights into workouts and sleep.
As wearable vendors compete on AI-driven personalization, the success of tools like Fitbit’s coach may depend on user trust, measurable outcomes, and sustained subscription value.
