The application includes 3 windows
The first window, which is a reception screen, includes the special code (a button) for the developer and the organization to which he belongs, as well as a second button that includes an explanation of what the application contains in a nutshell. Clicking on one of the two buttons takes me to the main page that includes a total of 13 mini stories for children. Clicking on one opens the third window in which the story is displayed for reading. The third window includes a button that allows to return to the main page to renew the selection.
The main page (that is, the second page that includes the titles of the stories contains a button that when clicked takes me back to the reception space.
