What do I need to know to become a mobile app developer?

[Hwe2]

Hi there, Please I'll like to ask what skills are required to become a mobile app developer.
My cousin wants to become a mobile app developer. She has no knowledge of HTML, CSS or programming.
I'll appreciate it if someone can list out the basic requirements or guide mova.io so I can forward it to her.
Thanks

Welp, your cousin can learn how to code (any of languages) or use app builders. Maybe she wants to get a job in some IT-company, then she needs to search if they have position and look for requirements.

The best way to learn how to build new app for mobile so you can suggest him to do some online study where he can learn coding and app development

Is there an easy way to learn coding and where to start? Being a naïve, I find it difficult to what to learn first and what is the route!!!
