Unlock Hanzi

Unlock Hanzi turns your Lock Screen into the easiest place to learn Chinese. One HSK word (pinyin, characters, and meaning) stays on your Lock Screen and Widget until you've truly learned it. No timers, no pressure. When you're ready, write it by hand in the app and move on to the next word. HOW IT WORKS • Add the widget to your Lock Screen and Home Screen • See the current word every time you check your phone • Open the app and practice writing it with your finger FEATURES • 5,000+ words from the HSK words list, ordered from HSK 1 to 6 • Self-paced: the word only changes when you say so • Handwriting canvas: write, clear, repeat freely • History of every word you've learned, with your own drawings • Day streak and progress by HSK level • No accounts, no ads, no tracking — everything stays on your device Chinese vocabulary sticks when you see it often and write it by hand. Unlock Hanzi builds both habits into something you already do dozens of times a day: glancing at your phone.
