## What is LeftThenRight?

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.

—— Comprehensive Character Libraries ——

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.

—— Tailored Custom Practice & Sync ——

Create personalized workbooks targeting your specific weak points or textbook chapters. Progress syncs seamlessly across your devices, letting you practice on your iPad and review stats on your phone anytime.

We are committed to continuously improving the product, and your feedback is our driving force! If you have any comments or suggestions, please feel free to leave a review in the App Store, or contact us via "Feedback / Contact Developer" in the App Settings.
