Anki Flashcard App

Anki uses spaced repetition, an algorithm that shows you cards at increasing intervals based on how well you remember them. The method is backed by decades of cognitive science research on how long-term memory works. Its interface is deliberately spare, a text field on the front and a text field on the back. The lack of visual polish is intentional because the developers prioritize the algorithm's effectiveness over the app's appearance. Anki works because it exploits the spacing effect, the finding that we remember information better when we review it at gradually increasing intervals rather than cramming it all at once. The algorithm tracks your performance on each card to calculate the optimal review schedule. Anki works where other study tools fail is that it removes the decision of what to study and when. The software handles the scheduling and you just show up and answer. Users have built shared decks for medical school, language learning, bar exam prep. Hundreds of other subjects, and that library of pre-made content means you can start studying immediately without creating cards from scratch. The desktop version is free and the mobile app costs $25. That one-time purchase for a tool you will use daily for years is one of the better values in educational software. The learning curve is steep because the settings are granular and the documentation is written for power users, but once you configure it the daily practice takes 15-30 minutes. Research supporting spaced repetition is robust enough that medical schools have started recommending Anki by name. That institutional endorsement from a community that depends on accurate recall gives the system credibility.
