Not very accurate
Native German speaker trying to find a good German app for my kids. This is not it. Just looked at a few of the phrases and found a mistake, or rather a phrase you wouldn't say like that in German. "A pair of underpants" in German would not be translated as "ein paar unterhosen". Unterhosen would be capitalized for one. It also technically means several pairs of underpants since pants in German are just singular, never "a pair of pants". Seems like they just ran the phrases through a translation program rather than using a native German speaker.
