FlashMe is a Flashcard Application that lets you create flashcards and organize them in Stacks called Decks. On top of that, you can add tags to each of your cards within a deck. You can manage your flashcard from the simple and straight forward interface.
The Best feature of the App is the Quiz feature. It allows you to Quiz yourself on all the cards in a deck or cards in a deck with specific tags. With each card, as you score your knowledge of each card, the cards that you rate as not knowing well will come more often the other cards.
