Yes, this is a knitting pattern gauge calculator that I made because I was tired of calculating by hand.If you are a knitter, you will have the experience of opening a knitting package and the size of the design and the size of your work are different.Its simple, but cumbersome, and its because of the gauge calculation that I dont want to do.I also recently had the experience of starting over from scratch after creating a work without paying a gauge.After that, when you enter CO, unconditionally! Calculate the gauge.This is a gauge calculator that I made because I was tired of making various works with octopus feet.If you have any comments about the app or knitting, please email us.(Landscape mode is not supported, and there is only a simple calculation function.)
