The Pixel Watch 4's new Gemini-powered fitness coach brings personalized fitness guidance

The Google Pixel Watch 4 has officially landed, and Google has introduced more than just sleeker hardware and the latest Wear OS 6. The company also announced one of the biggest Fitbit updates in years, including a brand-new Gemini-powered Personal AI Coach and a fully redesigned Fitbit app. The update aims to elevate Fitbit devices from passive trackers into always-on health and fitness companions that adapt to and guide users in real time.

At a glance, the new personal AI Coach is the highlight of the newest update. Instead of handing users a pile of data, it offers tailored fitness plans that change according to the data it collects. These plans take into account each user’s unique goals, history, and habits, adjusting over time. The coach also analyzes sleep data to provide detailed, personalized insights and adaptive schedules. Start sleeping better? Your recovery plan will shift. Fall off your workout streak? The coach may suggest gentler sessions until you’re back on track.

You can also talk to the AI Coach directly, asking virtually any health or fitness-related question. Whether you want to know if you should train after a rough night’s sleep or how to recover after a tough hike, you’ll receive an answer based on your personal data. The coach can also jump in during your workout, providing real-time tips based on your pace, heart rate, or recent activities.

Meanwhile, Fitbit’s companion app has been rebuilt from the ground up with personalization in mind. Goals take center stage, while deeper insights connect the dots between users’ habits and results. The app might reveal that endurance gains are coming from consistent long runs, or that late nights are dragging down readiness scores. As the AI Coach learns users’ patterns, the app adjusts its guidance to match progress or slumps.

The Pixel Watch 4 also benefits from smarter automatic activity tracking powered by AI recognition. Forget to hit “start” before a workout? The watch will log it anyway, identify the activity type, and deliver a full exertion summary, including cardio load and calories burned. With continued use, it becomes more precise, better recognizing your movements and go-to workouts.

Fitbit has long excelled at collecting health data. These updates align with other industry leaders and help move Google toward tracking that is more engaging, personalized, and responsive. And it’s not just for Pixel Watch 4 owners. The redesigned app will roll out to all Fitbit devices and Pixel Watches, with Fitbit Premium members getting a preview of the AI Coach in October 2025.
