Google Health 5.11 starts rolling out expanded activity detection to Fitbit Air and Pixel Watch

9to5Google reports Google Health 5.11 is beginning to roll out expanded automatic activity detection for Fitbit Air and Pixel Watch 3, 4 and 5. It covers more than 100 activities, including swimming and strength training; Google says detections will be nearly twice as accurate. BGR separately reports that Fitbit Air is slated to gain blood-pressure and insulin-resistance trend tracking for Google Health Premium subscribers, but those features won't provide on-demand readings.
