This skill counts rows and stitches with you for your crocheting or knitting project. Thanks to the voice interaction you do not even have to put down your work to record that you finished a row or some stitches. All of the counters are being saved also when you close the skill. So don't worry if you cannot get everything done in one go. Just come back to the project and resume where you left off whenever you wish.
Are you doing Amigurumi? Then I am sure this skill is particularly helpful for you! Whenever you have to grow every 5th stitch in a round of 50 stitches you might easily get confused especially when you do not have a stitch marker or you grew tired of it. Just tell stitch counter to count 50 stitches and every 5 stitches you say that you finished 5 stitches. And this is how you can easily keep track of your counting with keeping your hands on the project!
