Hi @980Panama

A a screen is a top-level container. Think of it as something like a webpage. An app can contain one or more screens. A screen acts as a container for galleries, forms and other controls.

A gallery is a control that shows a list of records.

A form is a control that enables users to view or to edit a single record.

The online help provides much more details on all of these objects.

There may other views but these are my perspective:
The basic function of a form is to take input from a user and send those inputs or enteries into the Datasource. This is a New form.
A form also help to edit what a User has previously entered into the Datasource. This is an EditForm
Finally, a form also helps to View what has previously been entered into the Datasource by the user. This is a Display or ViewForm.
A Gallery basically is used to display what a User has previously entered into the Datasource. In this a Case the function might match a display form.
However, a gallery could be used to display multiple Datasource at the same time through lookups and other functions.
So in displaying record in Datasource, Gallery is the way to go.
I will describe a screen as a Mother container or Bag that holds multiple controls including Gallery, Form and many other controls.
