Remember Everything You Learn
Stop forgetting what you study. Spaced uses science-backed spaced repetition to help you retain knowledge for the long term.
Why Spaced Repetition Works
Based on decades of cognitive science research, spaced repetition optimizes when you review to maximize retention.
Defeat the Forgetting Curve
Without review, you forget 70% of new information within 24 hours. Spaced repetition interrupts this decay at the optimal moment.
Study Smarter, Not Harder
Focus your time on cards you're about to forget. Easy cards appear less frequently, hard cards more often.
Build Long-Term Memory
Transform short-term cramming into lasting knowledge. Cards you know well can be scheduled months apart.
How It Works
Three simple steps to supercharge your learning.
Create Your Cards
Add flashcards with questions and answers. Use basic cards, cloze deletions, or reversible cards for flexible learning.
Review Daily
Spend just a few minutes each day reviewing cards that are due. Rate how well you remembered each one.
Watch Your Progress
Track your retention rate, study streaks, and watch cards graduate from "learning" to "mature" status.
