The Science of Learning
Flashcards are great for facts. Review is for everything else. It works with the materials you already have.
Fighting the Forgetting Curve
Our brains are wired to forget. Studies show that without review, we lose up to 90% of what we learn within just a week. This natural decay is known as the "Forgetting Curve".
Traditional cramming fights this battle with brute force, but it's exhausting and inefficient. The information doesn't stick, and you find yourself relearning the same material over and over.
Smarter Scheduling with FSRS
Review uses the FSRS algorithm to predict the exact moment you're about to forget a topic. Just mark a topic as done, and we'll tell you when to revisit it.
FSRS adapts to you. It analyzes your history—how difficult a topic was, how long it's been—and calculates the optimal next review date. The result? You spend less time studying what you already know and more time mastering what you don't.
