What Learners Are Saying

Teaching in Osaka and I wanted to connect with my students beyond the classroom. The everyday conversation scenarios made my Japanese feel natural, not textbook-y.

Moved to Tokyo and the polite vs. casual speech levels were killing me. This app breaks it all down with real scenarios. My coworkers noticed the difference in weeks.
