The Google Health app has replaced the Fitbit app, leading to a redesign that has affected user experience. Google is addressing user feedback by implementing enhancements and fixing bugs. Users can customize the Today page and Health tab by removing default tiles and adding them back in a preferred order, as drag-and-drop reordering is not available. Android users can add a Google Health widget to their home screen for quick access to key metrics, which currently displays weekly cardio, steps, readiness, and recent sleep data. The widget also includes a shortcut to the Google Health Coach for premium subscribers and a refresh button for data updates.
