Build Vocabulary That Sticks Forever
Transform new words into permanent memory with our intelligent vocabulary learning system. Choose your learning style and watch your vocabulary grow exponentially.
✓ Two powerful learning modes • ✓ Spaced repetition algorithm • ✓ Progress through four memory stages
Why Traditional Vocabulary Learning Fails
🔄
Endless Cramming
Reviewing the same words endlessly without understanding which ones you actually know and which need more attention.
💭
Forgetting Everything
Learning 50 words today but forgetting 40 of them by next week because your brain wasn’t given proper review timing.
🎯
One-Size-Fits-All
Generic flashcards that don’t adapt to your learning speed, preferences, or the unique difficulty of each word.
Nincha’s Dual-Mode Vocabulary System
Choose the learning mode that fits your style and schedule. Both modes use our proven spaced repetition algorithm.
Tap-Tap Mode: The Fastest Way
Perfect for quick reviews and building recognition speed. See a word, think if you know it, then tap to reveal the answer and rate your confidence.
Best for: Busy schedules, building word recognition, rapid vocabulary expansion, and daily review sessions.

The Four-Stage Memory Journey
Watch your vocabulary progress through our scientifically-designed memory stages
🆕
New
Fresh words you’re just discovering. Initial introduction with pronunciation and meaning.
📚
Learning
Building familiarity through frequent practice. Short intervals help establish initial memory pathways.
🔄
Reviewing
Strengthening memory with spaced intervals. Words are becoming more stable in your memory.
⭐
Mastered
Permanent vocabulary! These words are solidly in your long-term memory with minimal review needed.
Smart Scheduling Based on Performance
Rate each word as Easy, Good, or Hard and our algorithm automatically adjusts future review timing. Easy words disappear for weeks, while difficult ones return soon for more practice.

The Science Behind Vocabulary Mastery
Research shows that spaced repetition is 2-3 times more effective than massed practice for long-term vocabulary retention. Our algorithm implements the optimal timing intervals discovered by memory research.
The dual-mode approach lets you match your learning method to your goals: fast recognition building or deep recall strengthening.
