Study Smarter with Spaced Repetition
Create flashcards for any subject and study them using the Leitner spaced repetition system. Cards you answer correctly move to higher boxes with longer review intervals. Cards you get wrong go back to Box 1 for immediate review.
All cards are stored in your browser localStorage and persist across sessions. Import and export your decks as JSON files to share with others or back up your study material.
