In my opinion, this app seems especially awesome because of MathJax support. On the Mac, most scientists use LaTeX. They're used to it and know it well. But on their iPad, there's no LaTeX! On that platform, they're prepared to convert to Markdown (I was!)

Most iOS editors out there that pretend to be able to export Markdown to PDF do a ridiculous job: they export the plain text to PDF, without preprocessing the Markdown. Sounds stupid but that's what they do. Check Elements for a prime example. One of them does the right thing: Daedalus. But it doesn't support MathJax.

So my question is: is Marked available for iOS or do you have any plans to write an iOS version? I predict you'll have a big user base there.
