Flashcards

How flashcard review works

Each card shows a question or a picture. Think of the answer, then tap the card (or press Space) to check it. Rate how well you remembered: Again if you missed it, Hard if it took real effort, Good if you knew it, Easy if it was instant. Hygiene Atlas uses FSRS, an open-source spaced-repetition scheduler, to bring each card back just before you would forget it, so well-known cards come back weeks later and missed cards return the same day. Every card due today comes first, then up to your daily limit of new cards. Progress stays in this browser; the dashboard shows your streak and what you've mastered.
