An app ecosystem refers to the interconnected environment of applications that work together on a specific platform, such as iOS or Android. These ecosystems include not only the apps themselves but also the underlying infrastructure, development tools, and user communities that support them. This interconnectedness allows for seamless integration and enhances user experience. Within an app ecosystem, developers can create and distribute their applications, while users can easily access and utilize them. Major players like Apple and Google provide guidelines and resources to help developers succeed, fostering innovation and competition. This dynamic environment ultimately benefits users by offering a wide variety of applications tailored to their needs.
