Duolingo is an application designed to help you learn languages easily and comfortably, so that doing so doesn't feel like you're studying, but rather just having fun with one more game or app on your Android device.
The application allows you to learn a lot of different languages, such as Spanish, English, French, Italian or Portuguese. You just have to choose the language that you want to lean the first time you use the application.
One of the advantages of Duolingo, as compared to other language-learning applications, is the way that it uses the concept of 'gamification.' Duolingo presents the lessons in a way that makes it feel like you're just playing a game.
As you complete lessons, you earn experience points. If you make a mistake, it takes away hearts. Duolingo tries to make it so that your learning process just feels like a fun video game, and, luckily, it manages to do so.
Duolingo is an excellent tool to learn any language you're interested in, whether it be Spanish, French, Portuguese, or any other. In addition, it has an eye-catching visual style and it is totally free.
