Creating a website and would like to write on I phone using mark down

Hi all,
Previously I looked at some general writing apps for the iphone but they either didn't export the markdown to windows or documents such as voice dream writer and ia writer but now I am designing my own website and would like to be able to write in markdown and sync between windows and ios.
Does anyone know whether simplenote works with Braille displays or can anyone recommend an app which lets you type and navigate using a braille display only.
I don't want to pay for it as I will mostly be using my pc.
