These are just my personal notes as I was working through the New to ServiceNow training modules

In ServiceNow Developer, apps can be created using:

• Guided App Creator
• Studio (this article)

In ServiceNow Developer, select All > Studio. In Studio, select File > Create Application.

Give your app a name and select Create.

Notice at the bottom of the next window is a link Continue in Studio (Advanced). Click this link.

Select File > Settings.
