Those of you who, unlike me, own an iPhone, an iPad, or an iPod Touch may find the new Pinyin Typist Mac application of use.
Taffy of Tailingua had a look at this for me.
I’ve had a play with the Pinyin application and I’m generally quite positive about it. It’s clean, unfussy, and gets the job done. The automatic positioning looks to be flawless (i.e. typing zhuang1 gives you zhu?ng, not zh?ang)…. Overall though I like it, as it does what it set out to do without any showboating or unnecessary steps (excepting apostrophes).
Although I wish the apostrophe and hyphen were right there on the main screen instead of on a secondary one, the program allows people to do what they need to do: type Pinyin with tone marks.
