I left a comment on the App Store, but I'll reiterated and expand on it here...
I really like this calculator! I've tried just about every RPN calculator in the App Store and this is the one that is now on my home screen.
I like how it starts up quickly (although I suspect that you are just displaying a screen shot as the splash screen...) and how clean and uncluttered it is. Much better than my previous RPN calc of choice, PCalc.
My greatest wish would be to implement a 2 line stack display. I haven't seen many apps that go beyond the single line display, and it would be a very useful addition.
Another idea is to add a dedicated (non yellow function key) Drop button. If you don't think it would fit, maybe make the C key delete if you tap it, Drop if you hold it down for a moment?
Thanks for your suggestions and positive feedback!
Taking your points in order:
You're correct that the calculator seems to display a screenshot as the splash screen. This wasn't my intent! The version I submitted to the store has no splash screen, but what appeared on the store somehow wound up with a splash screen. I actually don't like having a screenshot splash screen, because the user might think the app is ready to go and try to use it, only to find that nothing happens. I plan to fix this in an update.
I can't promise a two-line stack display, but I have gotten other requests for it so I'm looking into it. Screen real estate is the main issue.
I agree that a non-shifted "Drop" button would be nice, so that you can quickly drop the stack several times. It's a matter of figuring out where to put the button while maintaining a sensible layout. I'm looking into that, too.
Thanks for a really great calculator. Have always loved the RPN logic but most are too complex and become difficult to operate properly on limited real estates of PDA's/I-phones etc Great work...it's on my I-phone over many others
I can't agree with the request for more lines of stack display. The single line is plenty, but then I've been using HP's single line RPN calculators for 30 years. The buttons are small enough as it is, and taking up space for more stack display would not be best, I feel.
Instead, I'd bring the x<>y key to the top level button functions. The "i" key is of little use, and it could be sacrificed for this. The only unique feature under the "i" key is the key click setting, but that could be placed as one of the yellow shifted key functions.
In addition to bringing x<>y to the top, I'd like to see the key layout of the Enter and the 4 basic functions to be that of the classic HP calculators. See the HP-35 and HP-21 at www.hpmuseum.org for an example. HP went away from this layout in their 10 series, and I never got used to that.
Excellent work, all things considered. It's now the calculator I use on my iPod Touch. Thank you,
With virtually all RPM calculators you can push the value you just entered onto the stack as many times as you like. For example you can do this: "3 ENTER ENTER" and 3 will be in the X and Y stack positions. This very valuable feature is lacking in the RPN X. Would you consider adding it? Otherwise, this is a fabulous calculator: simple, fast, crisp, elegant.
I fully agree with the last comment. Having used HP calculators (HP35) since they first came out, I was very happy to see this nice re-embodiment you provide. The only thing that puzzled me, and annoys me, is this lacking possibility to push the value onto the stack as many times as you push enter. Would be very nice if you could add it.

This is a very nice RPN calculator.
