The first time I saw this program I thought it may be the most useless invention since the one stringed banjo. However, on further inspection, I can see that Keycounter does have some practical use especially for writers who want to track when they are at their most inspired. Quite simply, Keycounter tracks the amount of strokes you've bashed away at your keyboard. The program tracks keystrokes per minute and whether the mouse has moved or not.
For writers, Keycounter is a useful way to see when you're at your most prolific although unfortunately, there's no way to tell what you were doing at a particular point in time - you have to make a separate note of that yourself so that you don't get your genuine writing activity mixed up with sending emails or leisure use. The results are displayed in graph format so you can easily see when your peak moment were. There is no way to export this data though it seems.
Simple and effective, Keycounter gives you full control over your keyboard activity and may help writers track their most productive periods.
