GoKawiilGoogle adds Health Guardian insulin resistance and sleep tracking to Fitbit Air
Google announced three new features coming to the Fitbit Air, released in May, alongside its unveiling of the new Fitbit Edge. The features fall under Health Guardian, a background health-monitoring tool in the Google Health app, with Premium subscribers ($10/month or $100/year) gaining access to insulin resistance estimates, blood pressure trends and sleep breathing quality trends. Health Guardian will also reach the new Fitbit Edge, though Google has not set a release date.
GoKawiil's interpretation of the reporting above, not reported fact.
By estimating insulin resistance from heart rhythm, sleep and activity data rather than blood tests or continuous glucose monitors, Google is pushing wearables further into preventive health territory without requiring medical-grade hardware. Locking the deeper metabolic and cardiovascular insights behind a paid subscription suggests Google sees recurring revenue as central to its health strategy, following a pattern set by other smartwatch makers. Users should note the company's own caveat that this is not a real-time glucose or diagnostic tool.
- Fitbit Air gets Health Guardian features including insulin resistance, blood pressure and sleep breathing trends.
- Advanced features require a Google Health Premium subscription at $10/month or $100/year.
- Health Guardian is also planned for the new Fitbit Edge, with no release date announced yet.
