Halcyon Touch Software is proud to announce that Halcyon Calc version 1.2 is now available from the iPhone App Store. The premier feature of the 1.2 update is the ability to plot expressions on an X/Y coordinate space. Directly interact with a plot by pinching to zoom in and out and swipe to move through the X/Y plane. Rotate your device and the calculator buttons disappear so the plot can fill the entire screen giving you more resolution. Buy it today on the App Store
Halcyon Calc is a full-featured RPN calculator for the iPhone and the iPod Touch. Among the key features of Halcyon Calc are complex number support and the ability to enter, evaluate, plot and find the roots of expressions. The calculator provides over 190 operations including trigonometry and logarithm functions. With simple programming support, the calculator allows you to create your own operations which you can use with the other built-in operations in expressions. The user interface is unique and takes excellent advantage of a touch based interface to allow you to quickly scroll through the stack, copy and paste values from the stack and page through operations to manipulate values on that stack.
Halcyon Touch Software was founded in 2008 by Jeremy Rand with the goal of providing wonderful software for the iPhone and iPod Touch platforms.
