About FlashDeck

FlashDeck — a clean flashcard app with a real spaced-repetition scheduler.

🧠 How it works: every card lives in a mastery box (0-5). Grade a card and it moves up or down; each box doubles the review interval (1 → 2 → 4 → 9 → 18 days). Cards you forget come back within the same session.

✨ Features
• Decks & cards — create your own, edit inline, delete
• Two starter decks included (World Capitals, Element Symbols)
• Study mode — flip cards, four-grade scheduling (Again / Hard / Good / Easy)
• Quiz mode — 10 multiple-choice questions built from your own deck
• Progress — reviews, accuracy, day streak, mastery histogram
• Everything saved locally; JSON export

🃏 间隔重复记忆卡：卡组管理、四档评分调度、选择题测验、掌握度统计，附两个示例卡组，数据本地保存。
