Monday Apple posted their Best of 2013 lists, including Music, Movies, TV Shows, Apps, Books, and Podcasts. The free Duolingo - Learn Languages for Free, was named iPhone App of the Year. And it's well deserved. Not only can you use it to learn Spanish, German, French, Italian, Portuguese, and English, but the app makes it fun. It uses gaming techniques to help you learn. And, interestingly, the app also has a crowdsourcing function, such that in the process of learning and doing translations, you are helping translate the Web into other languages.
