Baicizhan

Baicizhan is a Chinese vocabulary app built on image-based memorization: each word is paired with a picture and an example sentence rather than a bare translation.

That method suits recognition — associating a word with a visual context rather than with a Chinese equivalent — and is aimed primarily at students preparing for standardized English exams.

Word lists follow Chinese exam syllabuses, which is its practical advantage over general-purpose vocabulary apps for that audience.
