There are multiple ways to create a Jotform app, and one in particular is through the Form Builder. The form you just created or edited will be automatically added to the app.
In the Form Builder, go to the Publish tab. Scroll down, and click the Create App button.

You’ll be redirected to the App Builder with the form added to the app as its first element.

Note that the app will try to match your colors from the form. The icon will also be added based on the appearance of the form. You can adjust the design to match your branding.
