Designed for the A5 this Word Count Tracker for NaNoWriMo allows you to set your own writing targets.
Personally I have lower word count targets for the week and higher word count targets for the weekend. There are also days where I know I have extra time (or less time as the case may be) and my target word count takes that into account.
The tracker is a simple grid format – but sometimes simple is best – download your word count tracker for free.
