Actimeter

Actimeter is an application that tracks your computer activity and shows it on a traditional, easy-to-read meter.

Actimeter does this by counting the frequency of all your computer interactions or events: mouse clicks, keystrokes *, scrolls and mouse moves. It then calculates a score value on a scale from 0 to 100, using a carefully designed mathematical formula.

The score is calculated based on a time period that you can adjust yourself: the time period can be as short as one minute or as long as 90 minutes. Shorter periods make Actimeter react faster, longer periods give a more realistic view of your activity.
