I gave up trying to use the app because there are too many steps involved in dropping a card from the deck so that it's not given to the user again. The app became annoying instead of fun after I was given over 100 cards in a role that I already knew. Keep in mind some users will already know much of the material before using the app depending on their exposure to the target language. I also have essential trimmers in the hands so all that extra clicking to drop a card causes me physical pain after doing it for an extended period. Some similar flashcard apps give a drop button on the front of the card. I would suggest giving a drop button on the front of the card that gives a confirmation message asking the user if they are sure they want to drop the card from the deck. The confirmation message will insure the user does not drop a card from the deck by accident.

thank you,
