As much as I love pen and paper there are times when an app (or two) on your phone can come in really handy. Phone apps can always be a little tricky, some are free or have a lite version, whilst others have a small charge. And of course some aren't available across all platforms. But I thought I would have a little run through of apps I've used previously and that you might find useful.
Knit Companion: A very popular and widely used app for storing PDFs and tracking your progress, amongst many other things.
Bee Count: This is a really cute and functional counting app (android only though) which makes counting rows/repeats really simple.
Stash2Go: If you are a Ravelry user this is invaluable as it synchs to your Rav account - enabling you to check your stash/library on the go. There is still no official ravelry app so this is a useful fill-in.
Chart Minder: If you use a lot of knitting charts or like to create your own this is a great, free resource.
Toggl: Not specifically knit related. This gives you the ability to track the time you spend on individual projects. I love it for seeing where my knitting time goes.
