Decent language learning app. It doesnt really help you get conversational, but its a great introduction to a language. The app does have a "Bots" section that is SUPPOSED TO allow you to interact more naturally with the words you learn, but it only allows a very few words to choose from. It basically forces you to guess the response that the programmer had in mind when writing it. Of course you can always give up and press the help button, but then you dont earn any points for that response. Very frustrating.
