This app isn't just a list of random vocabulary words. There are categories for foods, drinks, land animals, birds and insects, plants, people/relatives, weather, emotions, phrases, and so much more! You learn by reading and hearing it which makes it perfect for adults or children who may not be readers. You can review your knowledge through fun games and tests for each category. I had no idea that I'd be getting so much for $7. This is excellent for those who, like me, have no prior knowledge or experience with the language.
