Fitbit is transforming with a new name and design, introducing the Google Fitbit Air, a tracker with an ultra-thin profile and advanced sensors that integrates with the Google Health app. The Google Fitbit Air can be paired with a Google Health Premium subscription for personalized insights and coaching. Users have control over their health data within the Google Health app, with options to manage and delete information, while Fitbit ensures that health data will not be used for Google Ads. The transition to the Google Health app will begin on May 19, featuring a new brand icon and app interface, with no action required from users.
