I just down loaded a counting app for my iphone called Knit Counter Lite. It was free and so far I love it. You can have multiple counts per project and multiple projects. You can also set perameters such as when performing cables you log in the number of rows between cable stitiches and it will automatically zero out so you can start the next set. There's also an area for project info such as pattern name, yarn, needle size and notes. Very cool!
There were a bunch of knitting apps available that I want to explore, if anyone has any reccomendation or reviews please post them
