Google to launch personal AI wellness and fitness coach for Fitbit and Pixel

September 16, 2025

Google has begun rolling out what it describes as a transformative tool in wearable health and fitness - a Gemini-powered personal health coach built into the Fitbit ecosystem, soon also working with Pixel Watches.

Set to launch in preview for Fitbit Premium users in the USA, this feature is part of a redesigned Fitbit app with coaching and AI at its core.

The new coach is intended to be more than a data dashboard, with Google expecting it to act as fitness trainer, sleep coach and wellness advisor all in one, adapting dynamically to the user’s goals, readiness and real-life constraints. For example, if a user logs poor sleep or feels less recovered after intense days, the coach might suggest lighter workouts or recommend extra rest. If injuries or schedule disruption occur, the coach can adjust routines appropriately.

Sleep receives particular attention in the redesign. Advanced algorithms will dissect sleep stages more precisely, highlight patterns affecting rest (such as delayed sleep onset or weekday vs weekend variations) and suggest personalised schedules. If fitness or activity levels change significantly, the coach may recommend changes in sleep timing or recovery days.

The revamped Fitbit app will also introduce visual and navigational improvements. Users of latest Fitbit trackers, smartwatches, and Pixel Watches will see cleaner data visualisation, better sync reliability, a more intuitive layout across tabs like Fitness, Sleep, Health and 'Today', and even dark mode. The idea is that the app becomes less about interpreting raw metrics, and more about actionable guidance.

Google is positioning this coach not just as a tool for reactive feedback but as a companion of sorts. Users will be able to “converse” with it: asking what to do if they’re feeling sore, whether to prioritize sleep over training, or how to adjust routines when life gets busy. It also integrates with broader health data platforms and compatible devices like smart scales or glucose monitoring tools - to give the coach a richer data set from which to offer suggestions.

Introducing the new assistant, built using Google’s Gemini AI platform, the company advises that the coach “constantly adapts based on personal health and wellness metrics and is uniquely tailored to goals and real-life circumstances.”

Beyond its introduction in the USA, Google has not revealed when the product will be rolled out in other parts of the world.
