Duolingo, the heavily funded startup best known for its range of online language-learning courses, has launched its standalone memorization app on Android.
The Pittsburgh-based company first introduced its Tinycards app to iOS last summer, but now the company is making the app available to millions more people with the Android launch.
Tinycards is essentially a flashcard app that uses spaced repetition to help users memorize things. Yes, this could be a language — Duolingo’s raison d’être — but it could equally be the periodic table or muscles of the body. Users can choose from existing flashcard decks or create their own.

Founded in 2011, Duolingo has emerged as one of the leading online learning platforms, though with a specific focus on language — it uses gamification to help people read, listen to, and speak more than 20 languages. The company has raised north of $100 million in funding and is now valued at $700 million, with backing from big-name VC firms such as Google Capital. It now claims more than 200 million users globally.
