iCalcy

While Windows comes with a built-in calculator, it isn’t necessarily the most beautiful app. iCalcy is a small tool that emulates the iPhone and iPod Touch calculator.
The app has a simple interface that should be easy to figure out, thanks to the intuitive layout.
As mentioned, the calculator looks like an Apple product, complete with the chromed rims and menu button. The calculator comes with several basic buttons, such as the digits from 0 to 9 and the basic math signs. Furthermore, like most calculators, it has several memory buttons as well.
By turning the calculator sideways with the help of the side buttons, you can access scientific features. For instance, the program can help calculate the sine and cosine, as well as the hyperbolic tangent, to name just a few.
The calculator can display nine digits in portrait mode and nineteen in landscape mode, including any separators.
The app is extremely similar to any other calculator, so if you’ve managed to work well with other tools, you should be able to easily figure out this one as well.
All in all, iCalcy is a nice program that is very easy to handle and useful to have around. Less experienced individuals shouldn’t have any troubles with this utility, thanks to its overall simplicity.
