Audio only flashcard application

AUDIO FLASHCARD APP: 1. Record your question and corresponding answer using just a single tap. No writing or photos..... audio only. The exception is the naming of each deck. 2. Play your recordings at a given speed in learning mode, (e.g. you can keep your Phone in your pocket while listening through earphones), 3. Test yourself: - Program plays your question, - You need to guess the correct answer in your mind, - Then, tap to play previously recorded correct answer - Confirm the correctness of your guess, so that the program can estimate the better repetition factor for current item. - Move on to the next item. =========================== * Using a spaced repetition algorithm( Leitner system) * Ability to make multiple decks * Ability to increase time before answer is given for each deck * Ability to specify the time (e.g. 2, 3, 4 ? seconds) between Q & A * Ability to add / delete / edit a card from any deck at any time * Ability to add / delete decks * Ability to activate a deck in a "learning or listening mode", where the entire deck can be listened to with each card being played. Also the ability to loop that deck for a continuous play. *** I have photos and very detailed examples for developer on file and will send later.
