saludos amigos de appinventor. (Greetings appinventor friends.)

I have a question which is

How to make an application created with appinventor 2 adapt to the screen of different mobile devices.

Set the screen Sizing to Responsive in the Designer.

Instead of using component Width and Height use PercentWidth and PercentHeight.

On the canvas, size sprites and other objects relative to either the Canvas Width and Height or the Screen Width and Height.

This includes FontSize.
