This is one of those apps that only its maker can love. Perhaps when the time comes that my back's to the wall with my life on the line.

However, being such a turn-off, I still have to motivate myself to learn how to program those function keys. And right now I'm in the market for a programmable scientific calculator, something akin to the Casio FX-502 of decades ago.

So why did I install it? It advertized itself as having 15 user-definable functions keys. And that serif font! What could the app developer have been thinking of?! Frankly, I can't wait to delete this from my phone. For now I'm fumbling and am not finding this calculator natural for me at all, having grown up with and gotten used to (semi)postfix calculators. Though theoretically a good idea, I seem to be having a problem deciphering how exactly it's to be done quickly and efficiently. Natural Calculator allows equations on the screen to be edited. The thing is, sometimes the slide method works, most often it doesn't. But for some reason it's implementation is quirky or something's not right with my Samsung or my index finger's a little too big for the 5-inch screen. Neither has RPN mode, as far as I can tell.Ĭalculator++ has a unique way of accessing the alternate functions of each key-sliding one's finger from the middle to one of the corners marked with the alternate functions. Still trying to get on the learning curve. These two are aesthetically pleasing, but using them is driving me up the wall. Am more used to postfix notation for these functions even in non-RPN calculators. For trigonometric functions and logarithms, among others, Hiper uses infix notation, ie., you have to press, for instance the "cos" key before entering the angle value.It just isn't natural for them to say, "I need a 2.2 million ohm resistor" or "1 x 10-9 ceramic capacitor." Quite useful for electronics designers who have to deal with capacitances in picofarads, nanofarads, microfarads, resistances in kilohms and megaohms, currents in microamps and milliamperes. Has an Engineering SI mode! It will, for example, show 10,000 as 10 k, 5.7 million as 5.7 M, 0.000764 as 764 u.

Free version already has fractions capabilities.

The number of significant figures makes me giddy: 15 digits on a phone in portrait mode and 32 in landscape mode, with the paid version extending that to 100, and the exponent's from three to nine digits.

Rectangular / polar conversion only in paid version.

Binary, hex, octal functions only in paid version.

On my phone it's 3 lines of registers in RPN mode and two lines in Algebraic mode

Stack doubles as data storage for statistics package (which includes min, max, mean, median, variance, std deviation).

Stack is accessible even in Algebraic mode.

multiplication, log, square root) performed, not just the numerical results of those operations

Keeps a history of the operations (eg.

The numbers and operations being keyed in (before pressing the equals key) is shown on an upper line with the intermediate and final result shown on the lower line.

Conversion function (eg., convert from m/s to mph, temp from F to K) has far more units than RealCalc.

Can generate random numbers (integers) from 0 to x, where x = any integer.

one default theme/skin (but it's sufficient with clear and crisp labels on the calculator keys).

Rectangular / polar conversion not available.

Doesn't keep a history of numerical operations, only the numerical results.

12-digit display is only in the paid version.

Fractions capability only in paid version.

Only one RPN style available in free verison, two other options only in paid version.

Customizable unit conversions and constants.

Binary, hex, octal functions included in free version.

In RPN mode, number of registers shown is adjustable just by sliding up/down.

I've been using RealCalc for a few years and so I'm biased toward it and tend to use it as my benchmark Click on the images to get magnified versions.

I've installed (and deleted) others but these are the more note-worthy (either because I like them, find them intriguing, or absolutely loathe them).
