The topics listed in this Extend Apps section, include developer concepts and detail to help you configure and customize template apps, and to also create your own custom apps.
Extend your apps
An app based on a template can be created entirely online in a browser, however, you can also configure this app further by changing additional settings, or customize the source code of the app, using AppStudio for ArcGIS (Desktop Edition) to make it entirely your own.
To learn about the AppStudio source code editing environment, see What is Qt Creator?
Create custom apps
When creating apps, you don't always need to start from a featured template. You can create your own app with AppStudio for ArcGIS Desktop Edition, piecing together components from existing apps and samples, or by writing the QML code from scratch.
To create your first custom app, see Create an app in AppStudio.
