How you learn
Four study activities built for active practice, not passive scrolling.
2
Word Recall
Retrieve Japanese words from memory to strengthen retention and build lasting learning.
Retrieval practice strengthens memory better than passive review.
3
Verb Conjugation
Practice conjugating verbs in different forms to master Japanese verb patterns.
Active production practice builds lasting memory.
4
Flashcards
Learn vocabulary and grammar with spaced repetition to build your foundation.
Foundation building that supports your output practice.
Why it works
Methods backed by research. Built for active practice.
Retrieval Practice
Recalling words and grammar from memory strengthens neural pathways. This builds lasting learning that passive review cannot match.
Production Practice
Creating your own sentences yields better memory than passive reading. Active output builds deeper understanding.
Spaced Repetition
Smart timing ensures knowledge sticks long-term. Our algorithm optimizes review intervals for maximum retention.
Built after five years of personal Japanese study and trying many different apps.
Zenshin focuses on what most apps still avoid:
- Real output practice without needing patient native speakers or expensive one-on-one lessons.
- Adaptive assignments that target your weak points, not random content.
- Clear progress tracking, so you actually know where you stand.
- No illusion of progress from hand-holding systems. Only practice that forces recall and real use.
