Free download with a free trial. Master Chinese Characters Stroke by Stroke. Focused. Precise. Built for Serious Learners.

Writing Hanzi is one of the most rewarding — yet challenging — parts of learning Chinese. Memorizing complex stroke orders, mastering character proportions, and getting accurate feedback usually requires a private tutor. This app gives you a calm, distraction-free digital studio to build genuine muscle memory and master written Chinese with confidence.

—— Real-Time Stroke Guidance ——

Advanced recognition algorithms guide your handwriting in real time. The app catches incorrect stroke sequences the moment your pencil touches the screen, acting like a patient tutor by your side to ensure you build correct muscle memory from day one.

—— Red-Pen Error Analysis ——

Review your practice at a glance. After each session, stroke order mistakes are automatically highlighted in red on your character summary, making it easy to spot weak points, review efficiently, and retain what you learn.

—— A Clutter-Free, Adult-Friendly Design ——

No cartoon mascots. No gamified sound effects. No childish pop-ups. Designed specifically for focused self-study, the clean, paper-textured interface eliminates visual noise so you can stay fully immersed in the structure and beauty of every character.

—— Authentic Feedback, Zero Auto-Smoothing ——

Enjoy a natural writing experience with full Apple Pencil optimization and realistic brush, fountain pen, and grid styles. We never auto-smooth or artificially beautify your lines — what you write is what you see. Honest feedback is the only way to achieve real improvement.

HSK Centric: Built-in HSK (Hanyu Shuiping Kaoshi) vocabulary sets tailored for foreign learners, from complete beginners (HSK 1) to advanced speakers.

Curriculum & General Standard: Includes standard character sets, traditional Chinese variants, and primary school literacy frameworks.

Instant Pinyin & Voice Search: Look up unfamiliar characters instantly by pinyin or voice, and save them to a custom practice notebook with one tap.
