Natural Calculator is an easy and handy tool used for different mathematical computations.

Pros: Natural Calculator is a calculator that not only can calculate the normal operations of an ordinary pocket calculator but has additional computation facilities such as trigonometric function, hyperbolic functions. One is able to do these calculations in degrees and radians too. Logical functions are another useful set. It has a very simple user interaction mode. It looks like a piece of paper and one writes the calculation like one would on paper in A+B = form. The calculator calculates the result depending on the operator beside the equal sign. One can write up a page of calculations, edit as necessary with the cut and paste tools available. You could save the sequence of calculations for later use too. Number of significant digits and the calculation precisions are preset. Calculations can be done even when numbers are represented in any one of the scientific, integer, fraction, and complex formats. User variable and functions also can be integrated into the calculations. Units conversion is supported. In a formula written on paper, re-computation happens automatically when any component is changed. Can be integrated to mathematical programs via the clipboard.

Cons: Some messages are not very correctly worded and may cause a little confusion. Besides one need to be a little bit careful against the classical version 1.0 legends.

Overall: A simple application with a range(but limited) of calculations possible. Easy interface. Overall a good rated 3 star application.
