■ Forgetting Curve Algorithm — You don't just memorize; you get memorized
Humans forget even words they have memorized over time. VocaKing uses the FSRS forgetting curve algorithm to accurately bring the word back to you just as you are about to forget it.
• The algorithm makes unknown or confusing words appear more frequently to ensure you memorize them completely.
• For words you already know well, it increases the interval between appearances to eliminate wasted time.
→ You don't have to struggle to memorize; the algorithm makes it easy for you to learn.
