Start with hiragana and katakana, then work up to N1 vocabulary and grammar, all in one app. [HIGHLIGHTS] Why Kotonoha • Everything in English: word meanings, example translations, explanations and AI answers, plus an English voice that reads the meanings aloud in autoplay • Complete JLPT vocabulary: N5, N4, N3, N2 and N1, 11,500+ words in total • JLPT mock exams: realistic section proportions, countdown timer, automatic scoring and pass probability • Grammar pattern bank: 465 JLPT grammar patterns from N5 to N1 • Kana trainer: all 208 hiragana and katakana characters, with stroke-order animations and native audio • Voiced, semi-voiced and combination kana fully covered, with KanjiVG stroke order • FSRS spaced repetition: scheduling based on the science of memory, so you remember longer and review less • Natural-sounding TTS Japanese audio for every word and example sentence • Original examples, usage notes and mnemonic hints, so vocabulary doesn't turn into rote memorization • 10 smart quiz types: fill in the blank, synonyms, word usage, grammar fill-in-the-blank, reading passage, dialogue listening, kanji reading, kanji spelling, meaning, and listen and choose • Kana readings and pitch accent shown, so you learn the right pronunciation and accent [HIGHLIGHTS] JLPT mock exams Mock exams modeled on the real JLPT: • Choose N5, N4, N3, N2 or N1 • Full mix of grammar, reading and listening • Countdown timer, instant automatic scoring, section scores and pass probability • If your connection drops mid-exam, you can resume (your question credits aren't wasted) Dialogue listening with synced transcripts Real JLPT-style listening questions, with male and female voices in synthesized dialogues. In review you can: • Change the playback speed (0.85× / 1× / 1.25×) • Open the transcript, which highlights each sentence as it plays • Tell speakers apart by color blocks, just like a real conversation FSRS smart review Kotonoha uses FSRS (Free Spaced Repetition Scheduler), a more accurate memory model than the classic Anki algorithm. It looks at how you answer each card and works out the best time to review it. No more random cramming: each word that appears is one you're about to forget. Reminders Daily review reminders, streak-at-risk alerts and a weekly summary. Premium subscribers get personalized reminder text based on the words you missed recently, instead of a mechanical "N cards left". At most one per day, so it never gets annoying. * Premium subscription Subscribe to unlock right away: • 10 smart quiz types and JLPT mock exams • 100 advanced AI uses per day (5 on the free plan) • 5 additional Japanese voices • Personalized study reminders The price is shown in the App Store before you subscribe.
