A powerful, flexible graphing calculator
Does far more than most calculators out there.
1) Scientific Calculator. Simple to grasp and easy to use, but powerful features are available when you need them. Available functions include the following:
• the usual arithmetic functions and exponentiation.
• square root, cube root, nth root, natural log, log base 10, log of arbitrary base, absolute value, factorial, permutations (nPr), combinations (nCr), modulus, random integer, bell curve, cumulative normal distribution, decimal to fraction.
2) Graphing. Capabilities:
• Graph up to four equations at once.
• Graphs are labeled.
• You can drag the graph or pinch to zoom in or out.
• Calculator can find roots and intersections.
• Graph in polar coordinates.
• Graph parametric equations
• Can graph implicit functions, such as x^2+y^2-4=0. Most calculator apps can't do this!
3) A unit converter. With a tap, you can enter the result of your conversion into the calculator. Currently converts different units of the following: acceleration, angle, area, density, distance, energy, force, mass, power, pressure, speed, temperature, time, and volume. Great for doing physics homework!
4) Constants for scientific calculations -- speed of light, strength of gravity at Earth's surface, etc. etc. etc. Tapping on a constant will insert it into your calculation -- i.e, you don't have to key in the value. Again, great for doing physics homework!
5) It can make a table of the values of any function you care to enter. You can choose the starting x value of the table, as well as how much x increases for each successive row.
6) Help screens linked directly to many of the available functions and constants. Tap the disclosure arrow to see the definition.
7) Forgot the quadratic formula? Or the double-angle formulas for sine and cosine? The math/science reference hits the high points of various subjects. Currently includes algebra, differential and integral calculus, geometry, trigonometry, vectors, vector calculus, and classical mechanics.
8) Keep track of significant figures [AKA sig figs]
9) Statistics -- enter data and make a histogram, box and whisker plot, or scatter plot with optional regression line.
If you are viewing this in iTunes, you will see five iPhone screenshots and five iPad screenshots. But even ten shots don't come close to showing everything this calculator can do.
I'd love to hear your comments or suggestions. You can write me at email@example.com -- but without the xyz. Thanks!

Difficult to get going
To start with it was difficult to understand and even a short sentence of explanation would have helped immeasurably. In maths x is traditionally lowercase italic, here next to pi it is shown to look like a multiplication sign. Changing this would have saved me days of exasperation. Once the penny drops it is impressive.
An effective graphic calculator without the costs. Was dubious at first, however the ease at which I found it to use and also consider this - how many of the functions on a graphics calculator do you really use?? This let's you plot graphs, calculate trig functions and loads more, which I would use on a graphics calculator. One of the great things us that when you want to check something it's actually got explanations of terminology etc, preprogrammed into it for reference!! This is great as I know most of it but being away from learning maths for 12 years has left me rusty on certain points, this is a brilliant tool- well done to the developers. If you're thinking about investing in one of those close to £100 calculators, have a go with this first, you might not be able to take it into exams though with it being on an iPhone, otherwise you could save yourself a packet!!!
This app is great! Its such a useful tool for any student of science or engineering. It's particularly good for examining complicated functions against similar expressions at the same time. I use this to plot graphs of functions I don't fully understand and then tweak the variables/constants to see what happens and learn how and where the curve changes. The only way it could be better is if it showed the expressions in the correct formalism, i.e. the way you actually write it down yourself instead of that awful linear type, which i just hate so much - not a problem though. It would be nice to add another variable too, e.g. f(x,y) with accompanying data table. Then it would be amazing! Right now I don't care, I'm upgrading to the full version stat!
