Most used knitting chart app

I use this app most often for making knitting charts. It has extensive stitch library; customisable grid and overall graph size; color vs symbols option; cross stitch, beading, or knitting chart option; import JPEG, export PDF, Mail, ability to add multiples of a stitch to chart with swipe, etc. One wish list item would be ability to darken graph grid and symbols.
