I own a yarn shop, and I use this app a lot (I also use and sell the pamphlet version.) The only thing missing is afghan yardage - afghans are in the crochet versions, and Id love to see them here.
I also disagree with the review who says the sizes only go to medium - the sweaters go up to a 54" chest, which is a 3X.
