With iDoRecall (iDR), users create spaced-repetition flashcards linked to the facts and concepts in their learning materials that they want to remember. When they practice memory retrieval, if they struggle with an answer, they can click to view the source learning file or video at the precise location where they learned it. “Learning materials” in the setting of iDR can be PDFs, Word-compatible files, PowerPoints, image files and videos.
