Productivity increases if the result is visible. The productivity of a writer, journalist, author is the number of words. Almost all applications in which you type text, somehow it is considered, some are better, others are worse, others are more visible.
I wondered if there was an application that would count how much I typed at all, in all applications. It turned out, yes, there are. Tried, tested and stopped at Word Counter for Mac.
What can I tell you? Perfect application, very nice interface and graphics, visually displays the number of words by day, by applications, there is a calendar where you can see how much was printed on a given day, you can add a specific file and track it.
I think the application is must have to writers
