The biggest thing this app has going for it is that its so easy and accessible. I can actually carve out enough time to use it, which is half the battle. Its great for building a basic vocabulary and learning the sentence structures of the languages. The biggest drawback is that it doesnt give you much practice with the back and forth of a natural conversation. Limited, but fun and helpful nonetheless.
