Fluency Tool: JLPT & Shadowing

Fluency Tool helps Japanese learners build speaking confidence with Echo Fluency, a hands-free shadowing loop that plays native audio, automatically opens the microphone, records your response, and scores pronunciation with speech recognition. A pitch accent visualizer highlights differences from native intonation, while incorrect sentences are re-queued for focused practice.

The app includes JLPT N5–N1 flashcards using SM-2 spaced repetition, a grammar guide with native audio and quizzes, and vocabulary games built from your own study decks. Content is organized across 25 JLPT sub-levels, with dashboard progress tracking and daily goals. Flashcards, games, and crosswords work offline; speech recognition and Echo Fluency audio require an internet connection. No subscription or trial is required, and an optional one-time purchase removes banner ads.
