Below are links to word count tracker apps and a link to a google spreadsheet for tracking tasks.
Word Count apps allow you to set word count goals over time and track your progress. They will show you what you've done each day as you move toward your goal through charts and graphs. They also recalibrate as you go faster or fall behind, so that you can see, for example, how many words you need to do each week if you've written more or less than expected. You can find apps like this that are built around communities and include motivational tools like badges. During NaNoWriMo becomes a community of folks writing a novel in a month. You can use the NaNoWriMo dashboard all year round, however. You can find year round online communities like NaNoWriMo, too.
Task Trackers are often spreadsheets where you can mark what you did that day. Word Count apps like those above don't let you enter other related writing tasks (although Pace Maker can allow you to set up a project such as "Editing Manuscript". In it, your goal might be to complete a certain number of pages per day).
My thought is simply this. I use a word count tracker if I know that I'm producing a certain number of words over time (per day, per week) to reach a goal, such as 20,000 words in six months. The tracker app helps me because it does the math (if I fall short one week, it alters word count goals for subsequent weeks) and represents my progress in different ways, such as a chart or graph. I use the Task Tracker spreadsheet to keep track of what I did. So, on a day where my goal is to draft, I can indicate that I have. But on the next day, when my goal is to review and organize my notes, I can indicate that as well.
Whether you use an app or a spreadsheet or both, you'll see that there is a space, often, to mark how you felt-- your energy level or your level of focus or, on NaNoWriMo, where you worked and how you felt. How you felt in a certain space or time of day can be useful information as you plan future work sessions.
