Spaced Repetition System
Review at the perfect moment for maximum retention
Cramming doesn't work. Spaced repetition does. By reviewing words at increasing intervals, you support long-term memory formation.
The Forgetting Curve
Without reinforcement, much of new information is forgotten within days. Spaced repetition exploits this curve by reviewing words right before you forget them—maximizing memory strength while minimizing wasted time.
How Rhythmica's Algorithm Works
Our system tracks your performance and adjusts review intervals dynamically:
- Easy words: Longer intervals (weeks or months)
- Difficult words: Shorter intervals (days)
- Forgotten words: Reset to frequent review
Optimized Review Schedule
A typical review schedule looks like:
- Day 1: Learn the word
- Day 2: First review (24 hours)
- Day 4: Second review (2 days)
- Day 7: Third review (3 days)
- Day 14: Fourth review (1 week)
- Day 30+: Long-term maintenance
Desirable Difficulty
The system ensures you review words when they're challenging but not impossible—the sweet spot for memory consolidation.
💡 Key insight: Struggling to recall (and succeeding) strengthens memory more than easy recall.
