## What is Lock&Learn Chinese?

Walk into the HSK already knowing every word on it.

Lock&Learn Chinese puts real HSK vocabulary on your Lock Screen and Home Screen widgets, the screens you already check a hundred times a day. Each word arrives with its character, pinyin, meaning, and an example sentence you would actually say, so the language settles in through your day instead of in one long sitting.

No account. No streak anxiety. Just the language, arriving quietly.

HOW IT WORKS
- Add the widget to your Lock Screen or Home Screen
- A new word appears each time you glance, rotating throughout your day
- Tap any word for the full entry: character, pinyin, meaning, and an example sentence with its translation
- Move through the HSK levels at your own pace

THE FEED
Open the app and keep going: the Learn tab is your deck as a full-screen feed, one card at a time. Tap to flip a card, swipe up for the next word, swipe left to save it, swipe right when you already know it. Every example sentence carries its pinyin word by word, right above the characters. The scroll you reach for anyway, made of vocabulary.

QUIZ
The Quiz tab deals your words back to back. Word rounds ask what a word means. Sentence rounds blank the word out of a real sentence. Listening rounds ask by ear: nothing to read, just the word spoken aloud. Getting one wrong never affects your progress. Choose whether rounds draw from the words you have met or your whole deck, and set each kind's clock, in Settings.

A QUIZ ON YOUR WIDGET, TOO
Prefer a challenge before you even unlock? Flip the widget to a question. It shows you the character and asks what it means, then reveals the answer with one tap. A tiny test every time you check your phone.

YOUR OWN LISTS
Every word carries a save button. Tap it to keep the word, hold it to file the word into a list of your own: travel words, exam words, the ones that keep slipping away. Your lists live in the Library, ready before your trip is.

YOUR PROGRESS
A Progress screen in the Library counts the words you know and the words you have met, keeps your streaks, and fills one bar per level as you climb. A quiet answer to how it is going, with no dashboard in sight.

BUILT ON HSK
The vocabulary follows the official HSK levels, the standard framework for learning Mandarin, from your very first characters up through the vocabulary of films, novels and headlines. HSK 1 is free forever, the whole first level, no trial and no catch. When you are ready for more, Lock&Learn Chinese+ opens every level.

MADE TO BE CALM
- Notifications are off by default and always opt-in
- Your progress stays on your device, no account needed
- Save words with a tap, or file them into custom lists of your own
- A calm, paper-like design that reads beautifully in light and dark
- Beautiful, readable characters in a classic type style

Lock your phone. Learn Chinese anyway.
