One Stitch at a Time is an easy to use app. It helps keep track of the number of rows while crocheting or knitting. You enter the number of rows that you need to complete. When the row counter reaches this number an alert will pop up and a voice will also notify you.
You can copy a pattern from the internet and paste it onto the text box.

Instructions are built into this app. There are no advertisements or additional costs. This app can also be used for other counting applications.

No annoying ads! Its just free.
