A SharePoint Designer workflow will run under the permissions of the user who started the workflow. Certain steps of the workflow may require the user to have more permissions than you intend to grant them. If elevated permissions are not used, the workflow will not work, and you will likely receive an access denied error or the workflow will not execute at all. The use of an App Step resolves this issue. Any actions placed inside an App Step will have Read/Write permissions to all Items in the site, such as site lists (which I will use in my example scenario).
