Create an App
You can create an app based on a template or completely from scratch. You can also create an app template based on an existing app. You can use the whole template or you can get configuration from a template or another app. The flexibility to quickly use and adapt existing components makes creating an app quick and easy.
To create an app:
In the taskbar, click File | New.
The New panel opens.
Select the template you want to use and click Create.
If you want to start with an empty layout, select Blank.
The Components panel displays all the components you can configure.
In the Components panel, click any component to begin configuring its settings. For more details about configuring components, see Component Settings.
When you click on another setting, any settings you have configured are automatically applied.
When you have completed the configuration of all the components you want to change, click File | Save As.
In the Title box, type in a title for your app, and then click Save.
The map is saved to either ArcGIS Online or Portal for ArcGIS.
