The new AI-powered personal health coaching feature in the Fitbit app is called the "Personal Health Coach". It is built with Google's Gemini AI and acts as a fitness trainer, sleep coach, and wellness advisor all in one. This feature provides personalized fitness plans, adjusts workouts based on real-time data, offers wellness advice, and adapts to individual goals and preferences. It will be available as part of Fitbit Premium starting in October 2025 with the redesigned Fitbit app and supports integration with Fitbit trackers, smartwatches, and Pixel Watches.
