WhatPulse is a computer program that monitors statistics regarding your keyboard usage and mouse usage. It tracks what keys you press and how many clicks you make with your mouse, including how far your mouse has traveled across the screen.
The program does not provide a lot of useful information about your computer usage, but it does provide numbers and information that is fun to look at and share with friends.
