This app was originally built to provide Traditional Chinese support when the OS did not support it. However, as of iOS 4.2, the Traditional Chinese input is now natively supported with the following input methods: Zhuyin, Cangjie, handwriting, and strokes. Please just go to settings and add international keyboards for these input methods. The app will remain online for users who prefer to enter Traditional Chinese using Pinyin (which Apple doesn't support). From now on it will also be free of charge and no longer updated.
