We built a Japanese Kanji learning app in-house that makes tackling one of the hardest parts of Japanese more enjoyable. The app uses spaced repetition to maximize retention while wrapping it in arcade-style gameplay, a custom narrative, and progression that adapts to your language level. It's designed for bite-sized sessions that fit into daily life, whether you're commuting on the metro in Tokyo, or just taking a break from work. Currently in beta, it's already helping learners get past the kanji hurdle without burning out.
