StudyBuff Makes You Earn the Next Flashcard

Field notes

StudyBuff ties spaced-repetition flashcards to six camera-counted exercises, with a fallback tap-to-log control when the camera cannot reliably see the movement. The page says each set advances the learner by one question, and that missed answers return during the session with an explanation. It also describes bot opponents with three speeds and friend matches over a local network, without accounts, servers, or a lobby.
