Duolingo is the leading mobile learning platform globally. With over 500 million downloads, our flagship app has organically become the worlds most popular way to learn languages and the top-grossing app in the Education category on both Google Play and the Apple App Store. For many, Duolingo has become synonymous with language learning: for example, on Google, people search the term Duolingo nine times more often than learn Spanish. We are particularly proud that our learners come from the entire socioeconomic spectrum, ranging from billionaires and celebrities to recently resettled refugees, a rare instance in which more money does not imply better access to a high quality educational platform.
