How can I have more than one frame?

I want to create another screen for my app, but I couldn't find how to do it

Hey @ruansantana, what exactly do you mean by creating another screen? Are you referring to a mobile app? If so we have some great docs here on working with screens and how to add new ones. If you are working with web apps your best bet is to link multiple smaller apps together using some of our navigation components mentioned here.
