Google Health 5.11 doubles workout detection range for Fitbit and Pixel Watch users

Google is deploying version 5.11 of its health application this week, a major shift that expands automatic workout recognition from 10 to 100 distinct activity types. The feature is live on Fitbit Air devices and Pixel Watch 3, 4, and 5 models. The Fitbit Edge will receive the same capability on October 27, when the hardware launches.

The update targets the common frustration of missed logs. Google states that the new system uses contextual reasoning based on user habits and past manual edits to improve accuracy. According to the company, this approach makes detections nearly twice as accurate and reduces missed workouts by more than half. Sessions lasting at least 15 minutes with a sustained elevated heart rate are logged automatically. A summary typically appears in the app within 30 minutes.

The system learns from user input. When a person confirms or edits a logged activity, the feature adjusts its future predictions. The expanded list includes strength training, swimming, and various racket and team sports.

Google Health Premium subscribers with Fitbit Air or Fitbit Edge devices gain access to two new Health Guardian tools. Blood pressure trends and insulin resistance trends can be configured immediately. The first reports are scheduled for release at the start of November. Blood pressure data requires wearing a Fitbit Air for at least five consecutive days in October. Insulin resistance trends, which track monthly metabolic shifts, require the device to be worn for seven or more days and nights during the month.

The app also renames the blood glucose section simply to Glucose. This change comes with updated charts. Users can set custom time-in-range goals for data from connected continuous glucose monitors. In the United States, Lingo by Abbott can now sync directly with the app. Glucose readings appear within 30 minutes of measurement. Premium members can ask the Health Coach questions about these trends.

Sleep tracking has received two specific refinements. The system now uses step data to better identify short awakenings, such as a trip to the bathroom. Users can also delete a nap entry that does not match their schedule directly from the nap card.

Version 5.11 is currently available on iOS devices. It is still rolling out to Android users.
