Flashcard Wallet

Master anything with intelligent flashcards that adapt to your learning.

Flashcard Wallet is a powerful, beautifully designed flashcard app that helps you learn and retain information using proven spaced repetition techniques. Whether you're studying a new language, preparing for exams, or mastering a professional subject, Flashcard Wallet adapts to your unique learning pace.

Three Ways to Review

SM-2 Spaced Repetition — Powered by the SuperMemo 2 algorithm, the gold standard in flashcard scheduling. Cards you struggle with appear more frequently, while cards you've mastered are shown less often, optimizing your study time for maximum retention.

Leitner System — The classic box-based method. Cards move through levels as you answer correctly. Perfect for structured, progressive learning.

Constant Repetition — Review every card in a deck until you've memorized them all in a single session. Ideal for cramming before a test or quick review before a presentation.

Privacy First

Your flashcard content stays on your device. All flashcards, images, and audio recordings are stored locally using Apple's SwiftData framework. No accounts and no cloud sync. The free version shows non-personalized Google AdMob ads, which may process device identifiers and ad-interaction data to deliver and measure ads; the app does not track you across apps or websites. Buying Pro removes all ads.

Flashcard Wallet — your knowledge, organized.
