Duolingo

There’s no doubt that Duolingo has quickly become one of the most popular apps for learning a new language in the world. Whether you want to learn Spanish, French, or even German, Duolingo has all these languages and then some.

What makes Duolingo stand out is its classes. You don’t necessarily take regular classes. Instead, you can take different quizzes and exercises to help you practice the new language.

Additionally, you can compete with other people to reach first place on the leaderboard. The first places will advance to other leaderboards where they’ll compete with other people as dedicated as themselves.
