The question is: how is the mobile application of a website / web application made? Is it made from scratch, totally separate from the site or converted in any way? If it's done separately, is it done as a hybrid or native app? And how is this "Data Synchronization and Updates" done (just a brief idea of how this is done)?
Thank you to those who respond!
Typically, large companies develop native apps. The backend of the app is the same as the site, so when you post a video on the youtube site, it also appears in the app. That's what webservices serves. Mark Zuckerberg, said that insisting too much on HTML rather than native development was a big mistake .
There is no such conversion per se, what some companies do is run the site within a web view in an app, Globo does this, for example. Google, on the other hand, has developed a native youtube app with the same features as the site, which gives the impression that it was "auto-generated", but it was not.
