card2brain features – flashcards go digital!


Your opinion matters! Since the first release of card2brain, we rely on a user-oriented development of the flashcard platform: First the web application, now the mobile app. Moreover, three types of questions, various upload options and formatting functions and a multitude of other features – such as adding co-authors, learning backwards or having things read out – have been added to the feature matrix since 2010.

Sustainable learning with the “5-compartment system”

card2brain's learning method is based on Sebastian Leitner's scientifically recognized “5-compartment system”. To start with, all flashcards are in the first compartment. All questions that are answered correctly are promoted to the next compartment, while all questions that are answered incorrectly are demoted to the first compartment.

Flashcards in the first compartment are reviewed in each learning unit. Flashcards in the second compartment are reviewed in every second learning session. All flashcards in the third compartment are revised every third time you set about studying and so on. Once all flashcards are in compartment number 5, this means that you really master your subject matter. Successful exams guaranteed!

Why don't you register for a free BASIC account, choose a set of public flashcards in the library and just give it a try.
