Learn German (Hello-Hello)

I feel that this app is very helpful .......many ways to approach the lesson ......my only suggestion would be to slow down the dialogue alittle .......it seemed rushed and sounded jumbled .

very good app

Unfortunately this app nixed itself from my consideration in lesson one when the introductions between strangers is taught using the familiar/informal you (du). In Germany, everyone uses the formal you (sie) unless mutually agreed upon or with children. It's disrespectful to use du with a stranger, an acquaintance, a boss, and usually coworkers as well. So why is "wie heißt du" the introduction form taught when you'll only ever use that form with a child?
