The news: Google will soon unveil an AI-powered personal health coach for the Fitbit app. Powered by Gemini, the health coach will be available to Fitbit Premium subscribers. Google will roll out a preview in October with the latest Fitbit trackers, Fitbit smartwatches, and Pixel Watches.

Digging into the details: The personal health coach will provide guidance based on the user’s goals, preferences, changes to daily activity, and health metrics tracked through their devices and apps.

• For example, if a person is working late and can’t make it to the gym, the coach will suggest an at-home workout with instructions.
• Users can also prompt the coach with questions, such as asking about the best stretching routine for someone with a stiff back.
• The coach will utilize health data from a user’s Fitbit or Pixel Watch, or from a user’s synced health and wellness apps.

Why it matters: Lots of consumers are already using mobile health apps and wearables with health-tracking capabilities.

• Over 94 million people will use at least one health/fitness app on their smartphones this year, per our projections.
• And we project that about 83 million people, or nearly one-quarter of the US population, will use a health-related smart wearable this year.
• Over half (54%) have tracked at least one health metric digitally, per a March 2025 Rock Health report.

Tech companies are moving quickly to develop AI features that drive a more personalized health experience.

• Oura and Whoop were among the first to add AI health coaches to their smart rings and fitness trackers, respectively. Oura also launched an AI Advisor with personalized health recommendations earlier this year.
• Apple is working on an “AI agent doctor” for its upcoming Health app revamp, per Bloomberg.
• Samsung is planning on introducing an AI health coach in its health app later this year.
