I’m writing this from the new WordPress iPhone app. It’s a pretty light, straight-forward interface. It allows saving posts locally on the iPhone before publishing or saving drafts to the server, enabling offline drafting.
There is even rudimentary photo support – but you can’t really control the placement or sizing of the image – it is merely appended to the end of the message. You don’t even see the image markup until it is published or saved as a draft on the server.
But even then, the limitations of the iPhone become clear – there is no copy/paste, and the classes that determine how WordPress displays uploaded images is unneccessarily complicated. (They should simplify that.)
So, though this is a pretty nice app, I’m not sure how useful it will be without more formatting options and copy/paste. For instance, I can’t even provide a link to it’s app store page. Also, why doesn’t the iPhone have characters luke curly quotes and em/en dashes?
UPDATE (from my Mac): Here is the link to the app.
