Google unveils Pixel Watch 4 with Gemini AI and Fitbit coach preview

Google unveiled its latest wearable updates this week, introducing the Pixel Watch 4 with upgraded hardware and deeper AI features while beginning a limited public preview of a Gemini-powered Fitbit Personal Health Coach for Fitbit Premium subscribers in the United States. The two moves together mark a push to combine improved sensors and longer battery life with conversational, AI-driven health guidance on Android-compatible devices.

The Pixel Watch 4, offered in 41mm and 45mm sizes, brings a brighter, domed Actua360 display with thinner bezels and roughly 16 percent more screen area, a new processor, upgraded skin-temperature sensing, and enhanced battery performance that approaches two days under typical use, Google said. The company also highlighted faster charging that can restore roughly 80 percent in 25 minutes, improved haptics, a louder speaker tuned for Gemini Live interactions, and dual-frequency GNSS for more accurate location tracking. Safety features include loss of pulse detection, fall detection, car-crash detection and optional satellite SOS emergency assistance, currently limited to the United States.
