Nihongo Boost vs Math Drills Mental Arithmetic

Nihongo Boost brings four Japanese tools into one app, with nothing locked behind in-app purchases. • Course — a 24-chapter story that follows Sato Misaki through her first year after moving to a new flat and a new job: neighbours, the office, a summer festival, a hot-spring inn, New Year. Every chapter has a dialogue with sentence-by-sentence English, grammar notes, vocabulary and a quiz, with polite and casual speech used naturally for each relationship. • Stories — five classic fables told in Japanese (Red Riding Hood, The Three Little Pigs, The Tortoise and the Hare, Peter Rabbit, Jack and the Beanstalk) with furigana, tap-to-translate and audio. • Flashcards — spaced-repetition decks of everyday Japanese words and grammar patterns. • Dictionary — search in Japanese or English, with readings and audio. Language Basics guides cover hiragana, katakana, kanji, particles and counters.
