Edito is a new markdown editor for the iPad.
For those of us who spend most of their time in Markdown, this tool allows to simply type a document using the Markdown syntax, and visualize its HTML equivalent immediately in a web-powered window, without leaving the app. In other words, it does the Markdown to HTML conversion in a breeze, and lets you email the resulting files.
The on-screen keyboard has a row of useful keys for Markdown. It also includes a web browser. No Dropbox integration (yet!), but I think they’re on the right track here and this could become a great way to write blog posts on the iPad.
