Unlock Hanzi shows one Chinese word at a time — pinyin, characters, and meaning — on your Lock Screen. You practice writing it in the app, then tap Learned to move on to the next word. Learning is self-paced: the word never changes until you say so.
5,000+ words from the official HSK word list, ordered from HSK 1 to HSK 6.
No. The app works fully offline. No data collected at all.
The widget updates when you tap Learned in the app. If it looks out of date, open the app once — this refreshes it. Removing and re-adding the widget also helps.
