Full summary
"Far and away the best free language-learning app." —The Wall Street Journal "We’ve also tried a few other methods such as book learning and Rosetta Stone, both of which bombed. That’s why I jumped at the chance to try Duolingo. And believe me, it’s addictive." —FluentIn3Months.com Duolingo is changing the way people learn languages. With Duolingo, you learn a language completely free, without ads or hidden charges. You have fun while you learn, leveling up and competing with friends. You have the opportunity to translate real-world texts in the language you are learning, and in doing so, help us translate the Web into other languages. Yeah, it's pretty sweet. Duolingo currently offers courses in Spanish, French, Italian, German, Portuguese, and English, and we are working to bring you many other languages. Stay tuned.
