What is spaced repetition?

Spaced repetition is a learning technique where you review material at increasing intervals. Instead of cramming, you review right before you'd forget — which dramatically improves long-term retention.

How does the SM-2 algorithm work?

SM-2 tracks how well you remember each card. When you rate a card as easy, the next review is scheduled further out. When you struggle, the interval shortens. Over time, easy cards appear rarely while challenging ones get more attention.

How do I rate my cards during review?

After seeing the answer, you rate your recall: Again (didn't remember), Good (remembered with effort), or Easy (instant recall). This rating determines when you'll see the card next.

Can I see my review statistics?

Yes. Each note shows the number of total cards, cards due for review, new cards, and mastered cards. You can track your progress over time.

Do I need to review every day?

Consistent daily reviews work best, but you don't have to be perfect. The algorithm adjusts when you miss a day. Even reviewing a few times per week will dramatically improve your retention compared to not reviewing at all.

Remember Everything You Learn

Spaced repetition schedules your reviews at scientifically optimal intervals. Review right before you'd forget — maximize retention while minimizing study time.

Key Benefits

Why learners love this feature.

Scientifically Proven

Based on the SM-2 algorithm, the same proven methodology used in academic research. Each card is scheduled at the optimal interval for your memory — not too soon, not too late.

SM-2 algorithm adapts to your performance
Review intervals grow as you master each card
Struggling cards repeat more frequently

Study Less, Remember More

Traditional studying wastes time reviewing things you already know. Spaced repetition focuses your energy on cards you're about to forget, cutting study time dramatically.

No wasted time on already-mastered material
Focus on your weakest areas automatically
Efficient review sessions that respect your time

Long-Term Retention

Cramming works for tomorrow's test but fails next month. Spaced repetition builds durable memories that last months, years, even a lifetime.

Knowledge retention measured in months, not days
Progressive difficulty builds lasting memory
Review history shows your retention curve
