Description
For students, engineers, scientists or people who fondly remember classic calculators, Halcyon Calc Lite is a great application for manipulating numbers and even symbolic expressions.
Features:
- Use this calculator on an iPhone, iPod Touch or an iPad
- Use your finger to quickly scroll through the stack to review intermediate results
- Copy and paste support
- Over 225 built-in operations, including trig, logarithms, real functions, complex operations and more
- Allows you to work with real, complex and integer numbers.
- Real and complex numbers can be displayed in standard, fixed, scientific and engineering format
- Integer numbers can be displayed in decimal, hexadecimal, octal and binary bases
- Work with real and complex matrices and vectors
- Enter symbolic expressions and solve them for different values. Even better, solve quadratic formulas, collect and expand factors and terms, find minima, maxima and roots of any expression.
- Plot symbolic expressions in X/Y coordinates. Pan the coordinate space by dragging the plot in any direction. Zoom in and out using a pinch gesture.
- Determine symbolic derivative, taylor series or numeric integral of an expression.
- Store numbers, lists, strings and expressions in symbols.
- Store statistical data and calculate totals, averages, standard deviations, linear regressions, etc over that data.
- Calculate the probabilities associated with standard distributions like the normal, F and T distributions.

Ratings and Reviews
Splendid Simulation of a HP-28S
This is a close to perfect simulation of the venerable and highly successful HP-28S, which is the grand dad of the most advanced series of HP’s scientific RPN graphing calculators. Being a genuine simulation and not a simple emulation working with the old ROM, this little beast is running at full speed and makes good use if the iOS’ native screen resolution and larger display. In brief it’s a charm to work with for anyone used to HP’s series of RPN calculators. It’s fully programmable, deals with complex numbers, matrices and arrays, and it’s able of plotting full screen, including pinch&zoom&scroll.
The developer has been implementing most HP28s functions, and the few that are still missing don’t hurt too much (e.g. the ALGEBRA menu, but for this one might be better of with a dedicated CAS system anyway). Only drawback is its name - no one would guess to find a full-fledged HP28 simulator behind something called Halcyon, and also the icon does not hint at its true origins.
So in brief this is highly recommended to any HP enthusiast. The original HP28 layout with the separate alphanumeric keypad makes it very easy to use. It runs natively and makes full use of the iOs graphics display and resolution to its advantage (gestures, copy, paste, scrolling etc).
