About Multi-Algorithm Intelligent Selection
Understanding the science behind WhenToReview's core innovation
What is Multi-Algorithm Intelligent Selection?
WhenToReview's competitive advantage: Unlike single-algorithm tools, we integrate 5 scientifically validated algorithms with automatic optimal selection and zero learning cost for users.
Core algorithms include:
- 50% Ebbinghaus Classic (140 years validated, proven reliable)
- 70% SuperMemo SM-2 (30 years real-world application verified)
- 90% Cepeda Optimal Intervals (2008 Science large-scale experiment)
Smart Recommendations, Effortless Experience
No more complex choices - the system automatically matches the best algorithm for you: intensive mode for exam cramming, gentle mode for rehabilitation, adaptive mode for long-term learning.
📱 Auto-sets 3-layer smart reminders (15min, 1hr, 1day before), export to any calendar app, never miss review time.
Core Advantages
Personalized review plans based on scientific algorithms to help you learn efficiently:
Intelligently matches the best algorithm, automatically sets reminders, making learning more effective.
