Chinese Annotator is a powerful iPhone application designed to assist users in reading Chinese characters. This app allows users to import ePub files and add Pinyin and English translations to the text in a 3-line format. With this annotation feature, users can mark which definitions and characters they already know on a word by word basis.

One of the standout features of Chinese Annotator is the ability to hide Pinyin or definitions of words that users already know. This feature encourages users to rely on their memory and recall the characters instead of relying on Pinyin. By doing so, users can improve their character recognition skills and enhance their overall reading proficiency.

Another useful feature of Chinese Annotator is the word list, which allows users to view all words, words with unknown definitions, or words with unknown Pinyin. This list of words can be exported to a file and imported into a flashcard system, such as Pleco. This makes it easy for users to identify and review words they are not familiar with in a publication.

Additionally, Chinese Annotator offers a convenient printing feature that allows users to print the page of the book they are currently reading. For users on iOS 10 and above, there is an option to print to PDF, providing a digital copy of the page.

Chinese Annotator is a valuable tool for individuals learning Chinese and seeking to enhance their reading skills. With its annotation features and word list functionality, this app provides an efficient and effective way to improve Chinese character recognition and expand vocabulary.
