Google seems to be focusing more on its screenless fitness wearable approach by adding new features. In a blog post, the company has now confirmed that it will be bringing health-tracking capabilities to the screenless Fitbit Air including the improved automatic workout detection to the wearable. The latest update introduces Health Guardian, a collection of tools designed to identify changes in health metrics over time. Google says these features will begin rolling out to Fitbit Air users with a Google Health Premium subscription later this month.Users who meet the monthly wear requirements will receive reports at the beginning of each month. Google Health Coach can use these insights to provide personalised wellness guidance and recommend adjustments to users’ fitness plans. What is the catch for using fitbit ?
