The Share widget allows you to share a 3D app by posting it to your social media account, sending an email with a link, or embedding it in a website or blog.
Configure the Share widget
This widget can be set to open automatically when
an app starts. Hover over the widget and click the Do not open this widget when
the app starts button 
to change the setting to Open this widget automatically when the app starts. (For widgets that you need to add to the app first, you can turn on this option after configuring the widget.)
To configure the Share widget, choose any of the following sharing options:
- Google+
If you plan to share the app publicly and want to share your organization’s URL, check Use the organization’s URL when sharing the app publicly. If this option is not checked, the arcgis.com URL is shared instead.
Use the Share widget

You can also use the provided buttons to post your app to your Facebook, Twitter, or Google accounts, or to add it to an email.
