Google Leverages Gemini AI and Fitbit Data for Future Smart-Glasses

Google has released a prerelease version of the Google Health app that replaces the legacy Fitbit app and embeds Google’s Gemini generative-AI model. The new app provides a subscription-based health coach that can summarize sleep, restfulness, activity trends and answer user queries in conversational form. The same AI-driven health data pipeline is expected to feed Google’s forthcoming camera-, display- and audio-enabled smart glasses.

Google acquired Fitbit in 2019, adding a wearables pioneer that has been on the market since 2009 to its portfolio. Over the past five years the company has integrated Fitbit hardware with its own services, culminating in the Gemini-powered Google Health experience. Gemini, Google’s large-language-model platform, is already deployed across Android phones and is slated for expansion to other hardware categories, including eyewear.

Embedding Gemini-driven health summaries into smart glasses could allow users to view real-time fitness data without a phone or watch. This integration would differentiate Google’s eyewear from Meta’s current offering, which lacks direct AI-driven fitness insights and does not sync Garmin data into Meta AI. Potential partnerships with eyewear designers such as Warby Parker and Gentle Monster could further broaden market appeal.

CNET

Some longtime Fitbit users worry that the removal of the standalone Fitbit app may erode brand loyalty, fearing that Google could “pull the rug out” from its original community. Meanwhile, Meta’s limited fitness functionality—particularly the absence of AI-based data synthesis—has been cited as a shortfall compared with Google’s Gemini advantage.
