I’m using iMockups for iPad to make the wireframes. Have you used it? I like it, except that it crashes every so often and loses a few minutes’ worth of work every time that it does. Also: sometimes I drag things I didn’t mean to, or resize things I meant to drag, with my clumsy, clumsy fingers. I like being able to do this work almost anywhere, though, and not having to sit at a computer. Today I worked on wireframes in the lounge at the gym while my boyfriend finished his workout!
