I can say it's great calculator with a lot of options and features. But this isn't everything. I can personalize it to my style and it's amazing. There are a lot of PCalc users, but I have my own. Buy it, if you want to be original.

Its simplistic beauty, the message it conveys, and how it inspires to do better, make for a harmonious continuity which compels me to try more in life.

It really is a great icon. Oh, the app's not half bad either. ;-)
