Tinycards is Duolingo's fresh and fun study companion app that can make you study and memorize anything.
You can browse Duolingo course decks (we are transferring the vocabulary over little by little), official Tiny decks created with a lot of love by our designers here at Duolingo, Staff decks, User decks, Student decks, or create your own. We chop up the decks into bite-sized lessons similar to Duolingo and you get a clean and fun learning experience. For free!
Right now it is only available for iOS on the app store, but you can sign up to be notified when it comes out on other platforms by visiting the website tiny.cards (select "Don't have an iOS device?" when you land).
You can also follow us on Twitter to get the latest news and awesome decks -- just follow @tinycardsapp
