Today it allows you to define data models and then auto generates views that you can use to perform CRUD operations.

This is a view of the app editor creating a simple Blog app:

After you define your data models, then you can create and edit live views of the data model.

Here is a screenshot of the Blog app where I am creating a new post:

I need to create a video of this to make it easier to show off.

The UX is still a bit rough, but the core pieces are there for building CRUD apps.

Thanks for asking!
