Duolingo, the world’s most popular language learning app, just launched its Android version, called Tinycards. Each learning session on Duolingo includes a variety of speaking, listening, translation, and multiple choice challenges. The app motivates users to stay on track by recording how many days in a row users spend learning a language. More than 20 different languages can be learned using Duolingo.
Tinycards for Android was developed by Luis von Ahn, staff product designer Gregory Hartman, and designer Jack Morgan.
