I do really like the app but I agree with podster - it was difficult at first to find where to download the lesson.
Also I thought "full lesson" meant that it would download EVERYTHING (lesson, dialogue, and vocabulary review) but that's not the case. The Full Lesson means it's the "full lesson" haha I guess I understand why because that's what it's called here on the website but maybe there should be an "Tour of the App" to explain this.
Also I wish the we could study the vocabulary in the lesson in a flashcard format.
Last two problems is that I find that navigating the lessons is quite slow, even on wifi, or even when the lesson is already downloaded & the "lesson introduction" doesn't work - whatever that is.
