How it works
Three simple steps to better recall.
Add cards your way
Type them, paste from a spreadsheet, import a shared category, or grab a ready-made deck from the Marketplace.
Review for a few minutes
Open your Due queue each day. Swipe through cards, grade your recall, and the algorithm handles the rest.
See real results
Cards climb from New to Mastered. Your daily load shrinks as knowledge sticks — proof the system works.
The science behind the habit
Research shows we forget new information rapidly unless we revisit it at the right moment. Spaced repetition targets that forgetting curve — scheduling each review just before a memory fades. The result: stronger recall in less total study time.
Consistency you can see
Each session ends with a clear summary: what you strengthened, what moved up in mastery, and what's next—so the habit feels rewarding, not endless.
