Technically, the Template for Citrix XenDesktop 7 supports XenApp 7.x https://apps.splunk.com/app/1751/
When the XenDektop 7 template was released, the name XenApp had gone away. Instead, Citrix decided to re-brand XenApp as XenDesktop App Edition. Citrix eventually brought back the name XenApp, but the underlying technology is still the same. So, the Template for Citrix XenDesktop 7 will work for XenApp 7.
