What is meant by Unpulsed or Pulsed???

Hi i am new to this platform.Can anyone explain what is the difference between pulsed and unpulsed countdown.How it is determined.Thanks.

Unpulsed is the amount of statistics which you haven’t sent to the website yet.

You can find more about pulsing here: http://help.whatpulse.org/kb/general/what-is-pulsing

Basically you upload your statistics online because local databases can be unreliable, so you can lose your statistics locally, but you still have them on your online account.
There’s also other benefits such as rankings, per-application data or viewing all your computers’ statistics in one place.
