WordPress for iPad and iPhone has two separate app extensions: one for publishing and one for creating a draft.
They’re both designed to help you quickly blog articles you’ve found. Most text style options are available in the draft screen that appears. Both will grab things like the page title and link, as well as any text selected on the page.
The publish extension will publish your post immediately, after allowing you to select a blog connected to your WordPress account. The draft extension sends posts straight to drafts. It’s a nice way to quickly collect posts in a single place to polish and publish later.
