Description
Don't just memorize Kanji. Master them
You’ve learned Hiragana and Katakana. You’ve tried the gamified apps. Now, you’re hitting the "Kanji Wall." Kaeru is the tool designed to break through it
Most apps teach you to recognize Kanji multiple-choice style. But when you look away from the screen, you forget. Why? Because you never built the muscle memory.
Kaeru is different. We combine Spaced Repetition (SRS) with Handwriting Input to force "Haptic Recall." By writing the characters, you create deeper neural connections, making retention automatic.
Native Stroke Order Practice: Learn the correct flow (Kakijun). Correct stroke order helps you distinguish similar-looking Kanji and read handwritten Japanese.
Smart SRS Algorithms: Stop wasting time on words you know. Our system schedules reviews at the exact moment you are about to forget them.
Curated JLPT Decks (N5-N1): No setup required. Jump straight into professionally curated decks for Kanji AND Vocabulary. Perfect for exam prep.
Zero Fluff: No cartoons, no leaderboards, no "fake fluency." Just pure, focused study efficiency.
iPad & Apple Pencil Ready: The most satisfying, tactile study experience on the App Store.
Note: Kaeru is designed for serious learners. Knowledge of Hiragana/Katakana is required to use this app effectively.
