Woah... I think you are too fast for me and my understanding of the matter. See me as a very old fashioned person who so far only knows pattern drafting on a table with pen and rulers, using also a dress-form, or wrestling with the fabric on my body :)

It would be awesome being able to do a pattern directly using the phone.
I do not use my phone though to blog (am only using my laptop. Would it also work with the integrated camera lens of my laptop? Do you know that? It may sound like a stupid question).

I am impressed that you built your own software (I've heard that CAD is truly difficult to learn).
