High CPU usage

I was running this app onto a MacBook Pro late 2011, OS X Mountain Lion 10.8.2 with 8GB of RAM installed. The app was easy to setup, and its very beautiful. It appears to be accurate as well. My problem with this app is that it uses a lot of CPU. Activity monitor shows that this app is running at 83% as I type this, and I can tell that the operating temperature has increased. I wanted something that would show the current temperature in my dock, but I cant run this app all the time if its going to consume so much CPU. I emailed the developer about this, and they wrote back saying that it was a bug that happens only on my Mac. Thats not true. It also happens on my 2011 Mac mini. This app is basically worthless if its going to consume so much CPU while running. WARNING! DONT BUY THIS APP UNTIL THE DEVELOPER FIXES THIS PROBLEM!
