Google’s AI-fication of the Fitbit app is charging full speed ahead and will soon reach more people and more countries. After debuting as an Android-exclusive preview for US Premium subscribers, Google announced a public preview of its redesigned Fitbit app and health coach/concierge the opening to iPhone users starting February 10.

the Gemini AI-powered “Coach” will also be launched in English to Fitbit Premium subscribers in the UK, Canada, Australia, New Zealand and Singapore on iOS and Android.

Google debuted the redesigned Fitbit app and built-in Coach as an optional public preview in late October for eligible Fitbit Premium subscribers on Android and has since been collecting feedback from early adopters to refine the experience. This expansion brings the new app to more people, creates more opportunities for feedback and moves closer to a final version release.

As the race to build smarter, more personalized health platforms intensifies, Google is leaning on an entire ecosystem of hardware, software and AI assistants to set Fitbit apart. With the pulse as the data center (via Pixel Watch and Fitbit trackers), Google aims to transform its platform from a passive fitness tracker to a proactive, AI-driven wellness companion.

What to expect

The redesigned app experience has a cleaner UI that is more intuitive to navigate than the previous version. It is built around four main tabs: Now, Fitness, Sleep and Health.

The Today tab, which is what you will always consult, highlights visible statistics with a stronger focus on weekly trends. Google says this is a more true reflection of progress compared to the usual daily insights promoted by other trackers. Other tabs allow you to dig deeper into detailed metrics in categories like sleep stages and vitals. And this time, the burden of interpreting the data does not just fall on the user.

Woven throughout the app is a new Coach feature, which you can access through the “Ask Coach” prompt. Coach takes real-time and historical data to help understand your metrics and turn them into personalized action plans. Google describes it as a “constant” coach that can answer questions or proactively adjust your plan based on recent activity, readiness, or even life events like travel or off-duty exercise.

For example, you might ask, “I have 30 minutes for a workout… What do you recommend?” or “How can I improve my VO2 max?” Or even draw links to your own stats with prompts like, “Do I sleep better on the days I get more steps?”

During the (optional) onboarding process, you can set goals, log available health equipment and write down injuries or limitations. The preview starts with a short 5-10 minute conversation (via text or voice) to help the AI ​​understand your goals and motivations. From there, the plan dynamically adjusts based on changing metrics like training load, readiness score and recovery data throughout the night, keeping everything aligned with your long-term goals.

Participating in the coaching experience is opt-in, so you can still use Fitbit without the AI ​​features if you want.

Availability and pricing

The update — first rolling out to US-based Android users — is also available to people in the UK, Canada, Australia, New Zealand, and Singapore (18 and over) who subscribe to Fitbit Premium ($10 a month or $80 a year) regardless of phone. Yes, that means iPhone owners too. It works with the latest Fitbit trackers, smartwatches and Pixel Watch models. During the preview phase, you can toggle between the old and new app designs without losing data, allowing for comparison and feedback collection.

Google says that user input from this period will be key to shaping the final outcome of the app experience and has an integrated feedback tool for tests. While the company hasn’t confirmed a firm end date for the preview, it says the experience will continue to expand to more users and devices over time.

The real test

This redesign and Coach feature shows serious potential. If it lives up to Google’s promises of bringing professional-grade coaching to mainstream users, it could mark a turning point for health tech and could put Google at the front of the pack. The company says the coach experience was developed with input from health experts and a consumer advisory panel, and that user data will not be used for Google Ads.

But as with everything in the AI ​​world, execution is everything, and the value of a health coach must be compelling enough — and accurate enough — to overcome the reluctance to entrust yet another AI component with sensitive health data. But the real test will be in how Google handles privacy, data security and real-world usability. That balance can mean the difference between a repackaged Gemini that turns most people off, and a game-changing tool that translates your data into action.

So far, it’s a good preview, but one I’ll be testing myself once it comes out.
