One of the tools I am using while knitting my socks is a row counter. After a decade of knitting I finally decided to buy one. My original method for counting rows or pattern repeats was tally marks. There is nothing wrong with saving the money and using pen and paper. I decided to make the change now because I have a toddler who likes to come and snatch things and its easier to keep up with one row counter than a pen, paper, and something to write on. I usually hide my row counter under my thigh so that he doesn't see it.
Most row counters I see are similar to the one I purchased, which is made by Clover. They count to 99 and then reset to 0. I have seen a few that will count to 999 and have separate number sections to count two things such as stitches, rows, or pattern repeats. I have also seen a few apps that have customizable counters. I also like the clicking sound they make. It is aural gratification that makes me feel like I am making progress. That click means I have just completed one more row, and then one more. It is much more satisfying than tally marks.
The only drawback I have found is that the top will sometimes get pressed if the row counter is bouncing around in my project bag. Then I have to spend some time figuring out which row I am on. This has happened a few times while working the chart for the socks I am knitting. I make a mental note of my last row at the end of my knitting sessions, but my brain sometimes fails me.
Do you bother with a row counter or use another method?
