Google is enhancing the Fitbit app experience for free-tier users, expanding access to the redesigned app initially available only to Fitbit Premium subscribers and Public Preview participants. The latest version, v4.60, introduces features such as weekly cardio targets, new Fitness and Sleep tabs, and a Health tab for deeper health data analysis. Users will be able to switch between the standard and redesigned app versions. However, certain features, like the AI-powered "Ask Coach," will remain exclusive to Premium subscribers. The changes are part of Google's commitment to health and fitness technology and will soon include a broader audience in the Public Preview program.
