Don’t buy: use Sublime Text w/ Browser-Sync instead

Byword doesn’t do much. In fact, the only thing it does that my preferred text editor doesn’t is let you type in “typewriter mode”. Instead of paying $12 for Byword, I suggest using Sublime Text with a plugin that can output markdown files as HTML and Browser-Sync to edit your files with live-previewing. All for free.
