I'm completely new to appgyver and coding in general. I would like to ask whether is it possible to integrate facebook or google etc. to my app? Best if it is free as I'm just a student.
Anything you can do on a website, you can do with AppGyver. What exactly do you have in mind?
Like the user can sign in with a Google/Facebook account and whatever data he inputs will be saved with that account.
Well yes, you can do that. It's called OAuth, there are plenty of JS libraries that will make it easier, but be warned that it is one of the more complex parts of web development!
