What's New in Japanese Reflex

2.0.2

August 13, 2026

WELCOME TO JAPANESE REFLEX 2.0 This is our biggest update yet, introducing new ways to train, measure, and strengthen your Japanese Brain. JAPANESE BRAIN SCORE Discover how automatically you can process Japanese. Each completed Reflex Drill now gives you a Reflex Score combining accuracy and response speed. Your five most recent scores across all 26 drills are averaged to calculate your overall Japanese Brain Score from 0 to 105. Can you raise your score above 90 and make Japanese processing fast, intuitive, and automatic? ADAPTIVE PRACTICE Practice now adapts to you. Adaptive Practice identifies the specific grammar skills and meaning patterns you miss, then gives you additional practice with those weak points until you can answer correctly and consistently. Rather than treating every question equally, each session focuses more attention where you need it most. JAPANESE BRAIN VOCABULARY Build the vocabulary you need to understand the Reflex Drills. The new Japanese Brain Vocabulary section includes integrated word study, readings, meanings, audio, example sentences, customizable review sessions, and self-assessment quizzes. FOUR NEW REFLEX DRILLS The Reflex Drill library has expanded from 22 to 26 drills, with four entirely new drills targeting important Japanese processing skills. We have also reorganized and improved the existing drill library, expanded Verb Transformations into five focused drills, and updated numerous questions, explanations, and answer patterns throughout the app. IMPROVED REFLEX TRAINING • Redesigned timing and scoring for a more accurate measure of automatic processing • New 2, 4, 6, and 8-second response-time settings • Improved audio timing so the response clock begins after the prompt finishes • Expanded and refined Particle Choice, Requests, Conditionals, Must/Don’t, and other core training • Better drill organization and navigation • Updated progress tracking across all 26 Reflex Drills NEW VOCABULARY AND GRAMMAR STUDY TOOLS The new JLPT Study area supports customizable audio review sessions and active-recall quizzes for vocabulary and grammar. Optional N1 Vocabulary and N1 Grammar packages are now available for advanced learners. PLUS • Updated layouts and navigation • Improved content installation and updates • Performance improvements and bug fixes throughout the app Version 2.0 transforms Japanese Reflex from a collection of drills into a complete system for building and measuring your Japanese Brain. Train faster. Target your weak points. Raise your Japanese Brain Score.

User reviews

Ok if you already have some knowledge

I love the setup of the app. Unfortunately, unless you already know kana it’s not very useful for things like the phrase drills.

Instead of a choice between just kanji and kana… it would have been worth paying for if Romani was an option.
