Learn and retain Japanese vocabulary for the JLPT, from N5 to N1. Sennin organizes your study into short sessions with spaced repetition (SRS). Add words to decks, practice with different quiz types, and review what is due each day. With Sennin, you can: • Study JLPT vocabulary from N5 to N1 • Listen to pronunciation and practice audio recognition • See readings, meanings, and details for each word • Organize words into decks and manage their learning status • Track progress by level, streaks, and study time • Set goals, reminders, and practice preferences • Use Light and Dark themes The Free plan includes unlimited new N5 words, up to 5 new words per day across N4–N1, and unlimited reviews at every level. Sennin Pro removes the daily new-word limit for N4–N1, lets you import text to create custom decks, and unlocks the Zen Garden and Samurai Ink themes. Sennin Pro is an optional subscription with monthly, quarterly, and yearly plans. Pricing varies by region, and you can cancel anytime through Google Play.
