good on iPad, bad on iPhone and Mac

Crashes within a few minutes of drawing. Just simple lines - too expensive to have problems like this. Wait for improvements, and updates, before Buying for the Mac. I have written to the developer via email and am waiting for a reply. IF they give me an answer within a day or two, I will refine my bad feeling about this app only if they fix the problems.
The only device it really works well on is the iPad3. Definately NOT ready for desktop use, there are not even instructions for use on the Macs.
