Is Duolingo Free (and Approved) for School to Use?
Duolingo is a science-based language learning platform that teaches its users to read, write, learn, listen and speak a new language. Its web- and app-based lessons are completely free. As with some free apps, however, Duolingo earns its revenues via advertisements that appear alongside the lessons and exercises. Those who wish to use the app without advertisements — or even those who just want to support the creators of the app financially — can subscribe to Duolingo Plus for a minimal monthly fee.
According to the app's website, teachers and even entire governments have deemed Duolingo to be a useful learning companion for language education. Whether you're interested for yourself or your organization, Duolingo could be right for you.
