About this app

It is a flashcard and spaced-repetition app designed for exam preparation, including anatomy, biology, SAT, GRE, AP, MCAT, USMLE, and finals. It combines active recall with detailed spaced repetition using Again, Hard, Good, and Easy ratings, helping students focus more on difficult material. It also supports image occlusion, making it especially useful for anatomy and biology diagrams, formulas, maps, and labeled images.

The app can turn notes, questions, mistakes, and other study materials into focused flashcards. Students can create decks on PC or tablet, review them on their phone, customize card designs, and use features such as PDF-based card creation and vocabulary pronunciation.
