Colossus is an advanced system monitor that is capable of displaying CPU, memory, network, battery, and hard disk storage information. Colossus also features customizable menu bar widgets, an animated dock icon, and a built-in memory cleaner.
Well i use System Monitor by Marcel B, same dev of TinkerTool System, and this application in my opinion is just a CopyCat of System Monitor.
Nothing advanced at all just another one pretending.. then given the fact its also a CrapStore I'm totally sticking with System Monitor.
Enough of those useless devs good only to copy others work/ideas.
While the app might be useful, my first impression was that the name is pretentious. While coming up with a good, memorable name might be difficult, given that there are already a number of apps that do the same thing, still Colossus is over the top, in my opinion.
