Understanding Spaced Repetition
Learn how Anki's intelligent SM-2 algorithm optimizes your study sessions for maximum retention and minimal effort.
🧠 How It Works
The Science Behind Spaced Repetition
Spaced repetition is based on the forgetting curve - the idea that we forget information over time unless we actively review it. By spacing reviews at increasing intervals, we can efficiently move information from short-term to long-term memory.
⚡ SM-2 Algorithm
Adaptive Learning Intervals
The SM-2 algorithm adapts to your performance:
- Again (Red): Card is shown again within 1-10 minutes
- Hard (Orange): Interval increased by 1.2x
- Good (Green): Interval multiplied by the ease factor
- Easy (Blue): Interval multiplied by ease factor × 1.3
Ease Factor
Each card has an ease factor that determines how quickly intervals increase. Cards you find easy will have longer intervals.
Optimal Timing
Reviews are scheduled just before you're likely to forget, maximizing retention while minimizing study time.
Day 1: Learn new card
Day 2: First review (if Good: next review in 4 days)
Day 6: Second review (if Good: next review in 13 days)
Day 19: Third review (if Good: next review in 34 days)
And so on...
Troubleshooting
Common issues and solutions to help you get the most out of your Anki experience.
🔧 Common Issues
Sync Problems
Issue: Cards not syncing between devices
Solution: Check internet connection, log out and back in, or force sync in settings.
Performance Issues
Issue: App running slowly or lagging

🎯 Optimization Tips
- Study consistently at the same time each day
- Don't skip difficult cards - they need more practice
- Use the "Hard" button when you struggled with a card
- Keep study sessions under 30 minutes for better focus
- Review new cards before old ones when possible
Frequently Asked Questions
How often should I study?
Consistency is key. It's better to study 15 minutes daily than 2 hours once a week. Aim for daily reviews to maintain optimal retention.
What's the difference between "Hard" and "Again"?
"Again" means you got it wrong and need to see it soon. "Hard" means you got it right but struggled, so the interval increases only slightly.
Can I study without an internet connection?
Yes! Anki works offline. Your progress will sync automatically when you reconnect to the internet.
How do I backup my data?
Your data is automatically synced to our servers. You can also export decks manually or use the full profile export feature.
Is there a limit to how many cards I can create?
No limit! Create as many cards and decks as you need. Premium features include advanced statistics and unlimited cloud storage.
