My original smartphone has some special apps.
I’ll tell you about two of them.
I have an RPG for fun.
I like an RPG games because they’re exciting.
I have an English app for studying.
I need it because I’m not good at English.
Of course, these apps use programming.
Programming is useful.
I learned how to move a rocket.
The rocket moves according to my programming.
Where will I send it?
