Nice app
Works good so far. It would be nice if it remembered the fix/sci decimal settings. Might be nice to have a key to scroll through the stack also.
Just got the latest update and the click sound needs to be able to be turned off.

Please, Morons, stop leaving reviews.
This is not the same as the iphone app. It uses rpn, which you dummies know nothing about. It's good, but a little to simple.
1.2 better but stack still broken
The current version corrects many of the bugs in the initial versions. Thank you. However, the stack still is broken: First a two-position stack on an RPN calculator makes the calculator not very useful. Second, the stack does not work correctly compared to other HP RPN calculators. Specifically whatever is entered in the y position on the stack stays there. Example: 2,enter, 2, + yields 4. Press + again and you get 6(!). What should happen is that the two arguements should be added (and cleared from the stack) and the result displayed in the x position of the stack. On my HP 25 or 48 the result is still 4 (the 48 gives an error message saying too few arguements.

Ideal for anyone used to RPN
This software works fine, and ideal for anyone well used to RPN, and who like me has trouble using ordinary calculators. Be careful with the FIX and SCI notation buttons otherwise you will be rounding too much and get silly results.
Beware of reviewers who don't understand what RPN is ! And by the way if you take the trouble to learn RPN it is much quicker and less accident prone than 'ordinary' systems; also no one will nick your calculator.

Owner
The primary advantage to RNP is the ability to calculate complex arithmetic expressions by simply entering them left to right using the stack (through the enter key). The limited stack depth of this application to one deep completely removes the entire advantage to RNP. Without giving you notice of this limitation, the results are just incorrect for stack entries exceeding 1 deep. Phenominal idea, great price, but very limited usefulness. HP should sell one that works!

App is flawed
When in scientific mode, one can not enter a number with a negative exponent.
Basic RPN - needs work
Easy to use, visually OK. Only has a two register stack. Problems with sticking in SCI notation. No click sounds. No memory.
I prefer the built in SCI calculator as an interface - better look/feel/function - if only it was RPN.

bit buggy
Seems to be no way to contact the author on his website so will do it here. Appears to have at least one serious bug. The FIX or SCI notation does not stick. I calculate $$ amounts but if I set it to FIX 2 and then do some multiplication it reverts back to SCI format - very not useful when calculating dollars and cents. Hopefully this bug will be fixed soon.

Does not work
Like KevinC123 mine seems to stick in SCI and does not allow you to FIX at 2, 3, 4 decimel places. I dumped it for another RPN calculator with a less desirable layout. My ideal would be something like this one in a horizontal mode but a super simple RPN calc in vertical mode (just the basic +, -, *, /, and inverse plus clr, clrx, and clear last character - this would solve the cramped keys for check book work etc).

A very good and handy app!
With respect to RPN and scientific functions this is a very adequate app.
I like that 'log' as well as inverse and hyperbolic trig functions have been included. Counter so some reviews it's always
worthwhile to have an extra calculator--that extra being a scientific _RPN_ calculator
