Learn Chinese every time you check the time: an HSK word on your Lock Screen, a feed that deals your words back, and quick quiz rounds that make them stick. 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. Lock&Learn Chinese+ is available as a yearly subscription with a 3-day free trial, a monthly subscription, or a one-time lifetime purchase. Payment is charged to your Apple Account. A subscription renews automatically unless canceled at least 24 hours before the end of the current period; manage or cancel it any time in your Apple Account settings.

Ratings & Reviews

  • This app hasn’t received enough ratings or reviews to display an overview.

New: choose how your Lock Screen widget looks. Pick Dictionary, Poster, In a sentence, Fill the gap and more, including Seal and Tone check, made for Chinese, plus new faces for the round widget. The meaning can now appear by itself a few minutes after each word, and you can switch to one new word a day. Your streak, saved words and Lock&Learn+ carry over untouched.
