At first glance, the default calculator built into iOS may seem a little basic to start with, but by switching into landscape more, extra options are revealed. This is something of an awkward means of accessing scientific functions, and Calcbot offers an alternative.

This calculator app features all of the basic functions you would expect to find, including an easy to read expressions history that displays a list of previous calculations.

For quick and easy everyday calculations, the standard app view is all you need. In order to access scientific functions and other operators, rather than adjust the orientation of your device, you instead need only swipe across the screen.

Calcbot may not include many more features than other calculator apps, but the way the interface has been implemented makes it one of the most pleasurable to use.
