Customer Reviews


This is a very user friendly widget, I use this tool in addition to istat, and the redings mirror each other, so it is also accurate. I run both widgets at the same time as a fail safe measure to ensure that I am always in the loop with what my Mac is doing. You will be just fine with either widget application, I am only siting that I have tested this application and can vouch for its accuracy. I am pretty new to computers my self so its nice to see what goes on in the background while I am working. You can check your local IP address, disk usage, tempature, CPU usage, and other useful tools displayed right at the top of your screen if you decide to set it up to display like I did. You can hide it too along with the other widgets if you like. I have no negative feedback at all.
