The story of apps
What are apps for SharePoint?
Apps are small, easy-to-use, stand-alone applications that solve a need for your users or business.
Site owners can install, upgrade, and uninstall them on their SharePoint sites without farm or site collection admins.
What are apps for Office?
Apps are web applications that extend what a document, email message, or meeting request can do in Office.
Run them in multiple environments like Office desktop applications, Office Online, and mobile browsers—in the cloud or on your site.
