Google officially announced on May 7 that it will deeply integrate the Gemini generative AI into its health and fitness ecosystem, marking a new phase in the brand integration since its 2021 acquisition of Fitbit. According to official information, the original Fitbit app has been officially renamed "Google Health" and simultaneously launched the screenless minimalist tracking device Fitbit Air, aiming to enhance the seamless experience of round-the-clock vital sign monitoring.

The core of this upgrade is the "Google Health Coach" service built on the Gemini large model. After one year of public testing, the service is scheduled to officially launch on May 19. Unlike traditional passive data recording, Google Health Coach can comprehensively analyze users' exercise habits, sleep quality, environmental factors, and nutrition intake, and even access medical records in the U.S. for multidimensional cross-analysis. Users can adjust their fitness goals in real-time through natural language and record their diet and exercise in the form of photos, voice, or files, achieving deep AI-native interaction.

In terms of business model, Google integrates this service into the monthly $9.99 (or annual $99) Google Health Premium subscription plan, and offers it free of charge to high-end subscribers of Google AI Pro and Ultra. This move not only closes the subscription ecosystem loop but also demonstrates Google's strategic consolidation in vertical application areas.
By moving large models from general interaction to specialized coaches with physiological data awareness, Google is leading personal health management from simple digital tracking toward an AI-driven personalized intervention era. This not only elevates the value ceiling of wearable devices but also provides an important model for the commercialization of generative AI in the field of biomedical health.
