I think it's too hopeful to learn the ins and outs of a language through an app alone. As you mentioned, Duolingo is a tool and very rarely does one tool fit all use cases. I see Duolingo as more of an interactive digital textbook, but as always there is a gap between completing exercises and applying your knowledge to the real world.
