cardFlash is a free flashcard app designed to help users study and learn various subjects. Developed by Chao Yu, this app aims to provide equal access to educational tools for all users. Unlike other flashcard apps that may require payment or display ads, cardFlash remains completely free and ad-free.

With cardFlash, users can easily import flashcard sets from Quizlet, making it convenient for students who already have sets created on that platform. If a set is not available on Quizlet, users can also create their own sets within the app.

cardFlash offers two study modes: Flashcard Mode and Adaptive Mode. In Flashcard Mode, users can go through the flashcard set just like they would with physical flashcards. Adaptive Mode, on the other hand, tests users with multiple-choice and writing questions to ensure thorough understanding of the terms. The algorithm in Adaptive Mode ensures that users cannot move on to the next term until they have mastered the current one.

The app also provides customization options for the Adaptive Mode, allowing users to adjust the algorithm settings according to their preferences. Additionally, cardFlash includes features such as easy editing of sets, 100% ad-free experience, Quizlet import, QR code set sharing, and folders for better organization.

cardFlash is constantly being improved, with upcoming features including image support, TTS support, and online sharing of sets. Users can also request new features or report bugs through the provided links.

Overall, cardFlash is a user-friendly and free flashcard app that offers convenient access to educational resources and effective study tools.
