This app helps you practice card memorization. MemDeck shuffles a deck of cards and shows you the order. You see the cards to memorize the order. The app records how long do you take to memorize the cards and automatically checks your answer. The results are recorded and you can check them later. MemDeck helps not only pro memory athletes but also beginners! You can reduce the number of cards and practice with a smaller size of the deck.
