Duolingo is the most downloaded education app in the history of the App Store. Our mission is to develop the best education in the world and make it universally available. Learning a new language is hard, but staying motivated is often the hardest part.

Our approach is grounded in efficacy: we continuously test and improve our methods to ensure learners make meaningful progress. We also believe in democratizing education by offering an effective, high-quality free product. Developing a great free product is essential to our mission, ensuring that anyone with a smartphone can access learning that works.
