Preety fun at the start, but as you go it gets annoying. This is a phrase learning tool, with no structure and very limited amount of courses in Premium version, at least for the one I've chosen. I have nothing to compare it with as this is the first app I've used to learn a language. Still, the amount of knowledge you'll receive is all based on memorising words with little understanding of language itself. I guess the name of the app says it all. For me not worth the money.
