I know this is a real beginner question to which most will probably answer that it depends on too many factors.
But assuming the following: you’re in your 20s, total beginner when it comes to coding, fairly tech-savvy, it’s been fairly easy to learn the basics of HTML, CSS and Bootstrap so far. You want to create an app for iOS and Android that is an interactive game. The user should be able to see animated objects and also have the ability to alter these objects or to move them around via the touch screen.
I don’t have the knowledge or the experience so far to know all the skills you need to be able to create an app like that. Can anybody with experience shed some light on what this path from total beginner to creating your own app would look like?
