iDoRecall is a new kind of spaced-repetition flashcard app. You upload your learning materials (many file types and videos.) You create flashcards linked to the concepts and facts in your study materials that you want to remember. When you practice, if you forget the answer, click a link to open the source file/video at the exact spot where you learned it. Quickly refresh your memory and get back to your practice session.<p>iDR now allows students to create study groups and share files and flashcards. Teachers can also create classes and do the same.<p>I'd love your feedback, positive and negative. Thanks!
