AppStore is an open application platform where SK Communications shares application programming interfaces (APIs), third-party developers provide applications, and users can add and use applications. The AppStore allows developers to register and develop applications using OpenSocial APIs and SK Communications' customized APIs. Registered applications will be available for users to add to their Minihompy profiles and interact with applications through social features like notifications, recommendations, and sharing with friends. The AppStore is aimed to provide a new user experience on NATE/CYWORLD through an innovative open social platform.
