Ratings & Reviews

  • This app hasn’t received enough ratings or reviews to display an overview.

What's new in v1.3.2: ◆ Refreshed onboarding — A cleaner, more minimal walkthrough with a slim progress bar so your first run feels lighter and easier to follow. ◆ Kanji level follows your goal — Switch your study goal between "JLPT prep" and "General" in Settings, and the kanji level scale now maps automatically. Level badges only appear when you're on the JLPT track. ◆ Minor design tweaks — Lots of small visual and usability touch-ups across Wordbook, Flashcards, JLPT Quiz, Search, the result screen, Handwriting, and more.
