It's freemium. You can download the full-featured app with a deck size of 50 (also enough to learn just enough words for a short trip for free). If you like it, you can add different increments to the total deck size through in-app purchases: 99 cents for +100, up to 14.99 for 3000.
Didn't mean to be tricky. I thought this was a good way to price it so everyone could try it, tourists could get what they needed for free, and every gradient of language learner could only pay for the amount they needed.
