A daily loop that actually sticks
Everything you need to keep Japanese in your life, and nothing you don't.
JLPT N5 through N1
The whole ladder, from your first hundred words to advanced vocabulary — study one level or roam across all five.
Right on your home screen
A native home-screen widget shows today's word at a glance. Learn a little without even opening the app.
Review that remembers for you
A spaced-repetition system (Leitner boxes) resurfaces words just before you'd forget them, so review time goes where it matters.
Make it yours
Color themes, Japanese fonts, light and dark. Tune the look until the daily word feels like home.
Yours, and offline
No account, no sign-up. Your progress lives on your device and the app works with no connection at all.
