What we mean when we say “world’s #1 language learning app”

At Duolingo, our mission is to make education free, fun, and accessible to all -- and we’re proud of it! So proud, we like to tout our success towards these goals in our advertising. But what exactly do we mean when we say the “world’s #1 language learning app”?

Specifically, we mean that we’re ranked #1 worldwide in both the Apple App Store and the Google Play app store by revenue, according to Sensor Tower.
