I'm doing final cleanup on the 1.6 update, which will be out sometime in July.
This will have export to PDF - which besides nicer printing and email, will let you open your socks in other apps - such as a pdf reader, or Knit Companion.
Next I'll focus on IOS7, making the interface work with the new look (transparent blue buttons on top of a blue background simply does not work) and adding a couple of shiny new features.
