This application does what it purports to. It allows you to write a question, blur out the answer, recall the answer in your head, and then click to see the answer. It however is missing some important features that should be standard in every flashcard app. (1) The allowed length for questions is very short. Exceeding the character limit causes the questions to go off screen and you cant see the rest of the question without several extra clicks. (2) There is no algorithm in shuffle mode that diagnoses you success rate on a particular card. The same cards you already know will continue to be shown to you over and over again. (3) Card stacks not exportable or importable. (4) Photos or screenshots can not be embedded on cards. (5) There is no formula editor for entering mathematical expressions or greek letters. The addition of these features would make this a 4 or 5 star app, but because of the missing features I can not give it more than a 3.
