I've been looking around for a coding project to keep my skills sharp, and my brother suggested the idea for a knitting app for smartphones. There is some math involved in re-sizing or changing patterns that's better done with a computer, but I was wondering what you would most like to see in an app for the Android/iPhone. Easy pattern maker? Lace design? Substitution guides for when you're in the yarn store trying to make a decision? Tell me, and I'll try to make it happen.
