Pinyinput

Pinyinput is an input method that makes it easy to type Pinyin with tone marks. You type 'Han4yu3 Pin1yin1' and Pinyinput outputs 'Hànyǔ Pīnyīn'. Pinyinput installs a custom keyboard extension on your device so you can use it to type pinyin in a simple and consistent manner in any application.
