Chinese Wubi Input app for iPhone and iPad

The Wubizixing input method (simplified Chinese: 五笔字型输入法) is a Chinese character input method primarily for inputting simplified Chinese and Traditional Chinese text on a computer.
The method is also known as 王码, named after the inventor 王永民.
The Wubi method is based on the structure of characters rather than their pronunciation, making it possible to input characters even when you do not know the pronunciation, as well as not being too closely linked to any particular Chinese dialect. It is also extremely efficient: every character can be written with at most 4 keystrokes. In practice, most characters can be written with fewer. There are reports of experienced typists reaching 160 characters per minute with Wubi.[2] What this means in the context of Chinese is not entirely the same as it is for English, but it is true that Wubi is extremely fast when used by an experienced typist. The main reason for this is that, unlike with traditional phonetic input methods, one does not have to spend time selecting the desired character from a list of homophonic possibilities: virtually all characters have a unique representation.
