WinOMeter

WinOMeter is a small and simple tray utility that allows you to measure your computer's activity.

It counts your keyboard / mouse presses and computes trajectory you have arrived by your mouse.

You can easily set it to run at startup if you would like to have capured all your activity.

Every day is saved into history, so you can make statistics of your activity (averaging..).

There is also export of whole history to a CSV file (comma separated values) which may be modified later in e.g MS Excel
