Almost Great
The organization of material, and its presentation are great. There is one technical flaw, however, and it is major, and inexcusable in this very expensive app. In neither the Lesson or the Conversation can you stop or go back to something that you are not sure of. In learning a language, there are ALWAYS situations where something specific is not clear and you need to confirm or correct what you just heard. It’s amazing that you in order to find that specific thing you need to double check, you have to finish the entire lesson or entire conversation, go back to the very beginning and listen to the entire thing again! That is a MAJOR technical flaw, and I am amazed that, although it has been mentioned by other reviews, it hasn’t been fixed. If that were fixed, this would be a 5 star app, now it’s only a 3 star app.
