Tinycards was a flashcard application available designed to facilitate learning of words or concepts. This was initially launched as an iOS application with future plans to deploy in other platforms or devices. Tinycards became available on a mobile friendly website in February 2017..
Tinycards was shut down on September 1, 2020. Duolingo has cited limited money and resources as reasons.  The company has made plans to integrate flashcard features in the main Duolingo app, akin to the defunct Flashcards feature.
We turned the experience into a game where you have fun unlocking new levels and keeping your memory strength bar full.
