So the criticism is that apps alone, without a web presence, cannot be "searchable" and "sharable". "Deep-linkable" is still possible; your app can handle and resolve URLs that another app could not. And I'm going to assume that it's the content of the app we're discussing, and not the app itself, since that's kind of trivial. So, the question is, without a web presence or API of some type, how exactly is data expected to be searched and shared by third-party participants? If the argument is that apps don't solve the problem of having a universal ontology, then I think the GP is not quite understanding just how intractable a problem that has been in computer science for a very long time.
