If you can already speak pretty comfortably, it’d be worth finding a tutor on italki or Preply to continue practicing. Similarly, because some of the languages have fewer levels, you might not benefit from Duolingo if you already have an intermediate or advanced level. There are also only certain features such as stories and podcasts for a few languages. Apps like LingoDeer offer more complete courses for less-spoken languages. Spanish and French are the most extensive, and have 10 different units, but Vietnamese only has four. Each language has a different amount of lessons you can complete. There is also a lot of focus on direct translation, which is not always the most effective way to learn a language, and leads to some strange phrasing.ĭuolingo is constantly improving, but some of the courses are not as developed as others. Other apps, such as Pimsleur and Glossika, use real speakers so you can hear an authentic accent. While it’s hard to complain about a free app, there are some things that Duolingo can work on.
