Tone-Colored Characters

Every character is colored by its tone — blue, green, coral, gold. Your brain builds an automatic visual-audio association. Over time, you see the tone before you think about it.

Spaced Repetition

Words move through boxes based on your performance. Get it right — the interval grows. Get it wrong — it comes back sooner. You always focus on what you still need to learn.

Frequently Asked Questions

What is a .wucai.json file?

It's a lesson package that contains vocabulary, sentences, and reading texts. When you open it on your iPhone or iPad, the Wucai app imports it automatically and generates all practice activities for you.

Can I edit lessons after importing them?

Yes! Lessons are fully editable inside the app. Add new words or sentences, remove content you don't need, or adjust anything — the practice games update automatically.

Do I need an internet connection to study?

No. Once you import a lesson, all content is stored on your device. You can study completely offline — on the subway, on a plane, or anywhere without Wi-Fi.

Can I share lessons with my students?

Absolutely. Create a lesson with the Content Creator, download the .wucai.json file, and share it via email, messaging, or any file-sharing method. Students open the file and it imports instantly.
