In SharePoint 2013 there is a special site collection that holds the apps called the App Catalog. There cannot be more than one App Catalog site collection in a web application or each web application can have only one App Catalog site collection. An app catalog is a dedicated site collection in a SharePoint 2013 web application (or a SharePoint Online tenancy) that hosts document libraries for apps for SharePoint and apps for Office. Administrators can upload apps for Office manifest files to the app catalog for use within their organization.
