I used to be able to carry on a conversation, but that was years ago. There are apps that can give you more than the basics. The one that I was playing around with a year or so ago didn't seem to have the pronunciation like I remembered it, but it was free. Here is the basics on Koreans, they have been bending people over for over 5000 years, we have only been at it for a couple hundred. If you take 10 Koreans and charge them one nickel to see an Elephant [bleep] in a coke bottle, three would walk off grumbling about having spent a nickel, four would demand their money back, and the remaining three would want want to buy the Elephant.
