Spaced Repetition Flashcard Trainer
Study your own flashcards with review times that adapt to your answers. Reveal each answer, rate your recall and return when cards are due.
How can I study flashcards with spaced repetition?
Add questions and answers, then practise the cards that are due. Think of the answer before revealing it and rate your recall as Again, Hard, Good or Easy. The scheduler uses each card’s review history to choose its next review time. Cards you forget return sooner, while well-remembered cards can wait longer.
