I like that I can learn at my own pace, that I can take the Duolingo app with me on my phone and that I'm learning another language (or two or three).

What I like best about Duolingo is the accuracy of the grammar. While there is a specific syntax they would like for you to master, the software is flexible enough to handle different variations of sentences with the same meaning. I also like how dynamic it is. You can never get bored going through the exercises.

The variety of languages available ensures that you will likely find a language you want/have to learn. The simplicity of the site and the app ensure that you will be able to learn at least the fundamentals of a language in your spare time. The website offers an impressive variety of languages. At the time of this review, there are eleven languages that are out of beta, two still in beta, and ten languages in active development. That's just for native English speakers! In addition to brief lessons that feature a mixture of vocal and written lessons, Duolingo features a remarkably innovative system where aspiring multilinguists can spend time translating works in order to gain a stronger grasp of their language of choice. The material consists largely of be online articles that touch on a variety of subjects, thus ensuring that the content to be translated will appeal to someone. Moreover, since this practice doubles as a business model, the website has a clean, simple interface bereft of ads or fees(there is an on-website currency called "lingots," but those are earned through achievements, not through exchange of actual money). In addition to the very reliable and functional website is an app available for Apple, Android, and (all three) Windows Phone users! The app is somewhat more minimalist, but is also very efficiently designed, and even has limited offline functionality.
