Plan when to review a flashcard using spaced repetition, the study method proven to move facts into long term memory. Instead of cramming, you review each card at growing intervals, so a card seen today comes back in a day, then a few days, then a week, then weeks apart, with each successful recall pushing the next review further out. Enter the date you first learned a card and choose a growth multiplier, and this tool builds a schedule of upcoming review dates in the Leitner tradition, showing the interval in days and the calendar date for each step. Everything is computed from your device clock in the browser with nothing uploaded. Use it to schedule reviews for vocabulary, formulas or terminology, to set reminders in your own calendar, or to understand why spacing beats last minute repetition.
It uses a Leitner style spaced repetition schedule, where each successful review pushes the next review further out.
Spaced repetition lengthens the gap after each correct recall so you review just before forgetting, which strengthens long term memory efficiently.
It generates the set of review dates for a card starting from the date you enter.
