Google has begun rolling out Google Health version 5.11 on both Android and iOS, a larger-than-usual point release that adds Health Guardian features to the Fitbit Air, expands automatic activity tracking, opens new glucose-tracking options, and refines sleep tracking. Google had previously signaled the update when it announced the Fitbit Edge.

Health Guardian Comes to Fitbit Air

Two Health Guardian features arrive with this build: Blood Pressure Trends and Insulin Resistance Trends. Both are tracked over time, so users receive frequent reports, and both track automatically when the Air is worn for consecutive days. Blood Pressure Trends requires five days of consecutive wear, while Insulin Resistance Trends needs seven or more consecutive days and nights.

Automatic Activity Tracking Gets the Biggest Lift

This may be the most consequential change for Fitbit Air owners. In practice, the device had become worse and slower at automatically tracking workouts, even two-hour sessions, and was slow to process any workout at all.

Google says updates rolling out to the Fitbit Air, Pixel Watch 3, Pixel Watch 4, and Pixel Watch 5 make these devices more intelligent, accurate, and reliable. The devices can now automatically track up to 100 different activities, up from about 10, including strength training, swimming, and racket and team sports. They also draw on more context — workout routines, historical data, and manual edits — to deliver nearly 2x more accurate detections and cut missed workouts by more than half.

Workouts that meet the minimum duration threshold (15 minutes by default) with a sustained elevated heart rate are logged automatically, with a summary sent to the Google Health app, typically within 30 minutes. When users confirm or edit an activity, they improve a feature that learns their patterns and uses them to refine predictions.

More Glucose Tracking Options

Glucose tracking sees several changes. Blood glucose is now called Glucose throughout the app, so charts and graphs should be checked for updates. Users can set custom time-in-range goals for glucose data from connected continuous glucose monitors by going to the Metabolic section of the Health tab, tapping Glucose, opening Settings, and selecting Set goal.

For US users, Lingo by Abbott can now connect directly to the Google Health app, with glucose data displaying within 30 minutes of a reading. Google Health Premium members can also have Google Health Coach answer questions about glucose trends. Connection is made by tapping the profile icon in the Google Health app and selecting Partner Apps.

Sleep Tracking Refinements

Sleep tracking now factors in steps data to better capture short awakenings, such as getting up to use the bathroom, improving awake detection accuracy. Naps that do not match a user's day can now be removed directly from the nap card.

What to Watch

The update is rolling out now on both Android and iOS. The activity-tracking overhaul is the piece worth watching: Google is promising roughly double the detection accuracy and fewer than half the missed workouts across four device lines, a claim users can verify against their own logged sessions in the coming weeks.
