App catalog is a separate site collection like team sites in SharePoint for configuring and managing SharePoint Store and its setting. This site collection is basically used for deploying custom apps which are developed for internal organization and makes those custom apps available in SharePoint sites to users to browse as well as add it. Users can search the deployed or installed apps from site by add app option under From Your Organization.
