Another flashcard app? Yes... but built a little differently. Fast Flashcards includes the features you'd expect: spaced repetition, flexible deck creation, folders, and progress tracking. The difference is simplicity. No subscriptions. No advertisements. No accounts. Unlock unlimited decks and folders with a single low-cost in-app purchase. One deck can be edited, deleted and re-added on download. Set a daily study goal, build your habit, and let the app handle the scheduling.
