This is a Chinese character conversion app.

In order to convert the Chinese characters, you can hold the smartphone with one hand and use the pen to write the Chinese characters with the other hand.

As the user interface is very easy to operate with one hand, it is also useful when writing documents with one hand.

Furthermore, the history of the expanded strings can be saved, and the strings can be called at any time previously.

In addition, this app allows you to enlarge the input string from another application.

You can do it by entering the URL of the page that contains the image to be enlarged in the expanded string field.
