The primary purpose of App Groups in app development is to allow apps to share containers and communicate. This functionality is particularly important when developers want to enable multiple applications, or different parts of a single application, to access shared resources, such as data files or user preferences. By establishing a common container, app groups facilitate seamless data sharing between applications that are developed by the same developer or are part of a related set. This can greatly enhance the user experience by maintaining consistency and continuity across different app interactions.

While enhancing app graphics, tracking app usage statistics, and creating independent applications are important aspects of app development, they do not relate to the specific utility of App Groups. App Groups focus on collaboration and data sharing among applications rather than individual app performance, graphic quality, or independence.
