I just saw this program today (I guess it used to be iDraw). It caught my interest because the price is only $25

It runs on Macs, iPhones, and iPads and appears to be a really nice vector graphics design tool.
I am interested to see if anyone has used it and how well the files import into Easel or Vcarve.
What! I just bought iDraw like 3 months ago! I like using it, it lacks some functionality I would like but all in all its pretty solid.
It’s too bad not for PC. 
That’s rare! Usually it’s the other way around!
I use iDraw (now called Graphic) on my iPad. It works great and is pretty feature rich for an iPad vector app.
I just got an email response from iDraw/AutoDesk and they said all current users of iDraw will get upgraded to Graphic for free. He also mentioned that they are working on more features to release!
