Would it be possible to make an offline application that runs code like Code Playground? Also, how and what files are needed?

Question

So, after revisiting Ruby twice I realized how annoying and inconvenient it was to try to test out my codes after making them when I didn't have internet. What coding language would I have to learn to make it possible to run Ruby code like the software for Code Playground? I plan to make an offline aplication for Android, and its general focus is to run Ruby code, and create .rb files as well as run any .rb file, all offline and no internet required. For free. Well, there would be extra ffeatures

Answer 1

Also, instead of just downvoting my answers/questions, why not give me some helpful feedback? It would reeeeally be helpful.

Answer 2

Okay. Would you download the latest Ruby gems and put them into the database?

Answer 3

And yes, I know about Termux, but it's too complicated in my opinion. And once I learn other languages, I plan on making offline apps to run them as well. I just want an app that runs ruby. Simple, clean, now frustrating file management crap.

And this is also my first project as well. My "tribute" to the Ruby coding language in a sense lol also the only "paid" part of the app would be optional crap. Like...idk. Saving codes to the cloud for backup.
