Hanzi Fog: Tell Hanzi Apart

Hanzi Fog helps you learn Chinese characters by doing the one thing flashcards alone can't: telling apart the characters that are easy to confuse. LEARN BY DISTINGUISHING Most apps drill characters in isolation. Hanzi Fog puts one character at the center and surrounds it with a soft "fog" of the ones it's easy to mix up — similar in shape, sharing a radical or component, sounding alike, or close in meaning. Seeing them side by side is what makes each one stick. EXPLORE THE FOG Tap any character to move it to the center and reveal its own circle of look-alikes. Filter by the relation types you care about and follow the connections as far as you like. LOCK IT IN - Spaced-repetition (SRS) flashcards for the characters you bookmark - Quizzes: multiple choice and "spot the odd one out" - Bookmarks and seen history so nothing slips away MADE FOR YOUR LEVEL Pick an HSK level and Hanzi Fog surfaces characters that match it. Meanings, flashcards, and quizzes are available in English and Vietnamese. PRIVATE BY DESIGN No account. No ads. No analytics or tracking. Your bookmarks, review history, and settings stay on your device, and the app works fully offline. Built on trusted open data: Unihan, CC-CEDICT, Make Me a Hanzi, and HSK 3.0 vocabulary.
