My favorite app on the iphone was this calculator. Does it exist? Id pay $20 for such an application on Android.

anyone else. i know hp actually put out one ofthe versions of the hp on the iphone. amazing to me the cult following on this calc.
Hard to believe - the 12c introduced in 1980/1981 - one of the premier technologies at the time (keep in mind, no one had cell phones then)... and for it to STILL be a current product ~29 years later - amazing - what other electronic product has had anywhere near this life?
I'd love to see a 12C Droid app. Tried downloading the RPNCalc free app, but it doesn't have a fin calc, and the website provided just errors out.
What about the HP 48? It is using reverse polish notation, too. The android app is named 'droid48' an can be downloaded free in the market.
Hi all; I'm the author of RpnCalcPro. It doesn't have the same layout as the HP12C (I intended to use it in portrait mode), but it has all the same functions except for programmability. It's $5 at present. More info at RpnCalc Pro
I've gotten some feedback from people asking that I make they layout exactly like an HP12 in landscape mode, so I'm working on it. It's a little tricky because an android screen is much smaller than a real HP12, so squeezing it all in is rather difficult. I have it working now for the Archos, and with a little tweaking, I can get it to fit on G1 and Droid. Look for the new layout soon.
Since I have a number of interested people here, I'd like to do a quick user survey:
Do you use the programming functionality of the HP12? I haven't seen a need to add it to the calculator app, but I might if there's a demand.
Do you find the HP12's n,i,PV,PMT,FV functions ambiguous? That is, do you have trouble knowing if the key will enter a value, or compute it? (I added a "Find" key to my calculator to remove the ambiguity, but maybe it's not needed.)
Also: the cash-flow calculations (Cf0, Cfi, etc.) Do you ever use these? Do you edit the stored values? Do you change the Ni values?
Other differences between the android app and the real thing: I have 20 memories, whereas I think the real one only has 10. The stack has 16 levels instead of 4. Statistics have their own registers rather than being stored in the main memory registers. I'm going to guess this doesn't cause anybody problems.
In general, I'm interested in whatever feedback you might have.

The Find button is an interesting one. Personally I don't think you need it. It feels like just pressing "PV" for present value (like on a 12c) is 1 less button click than "Find"->"PV" on RpnCalc Pro.
FYI... I received the following email response to my inquiry as to whether Lygea would be developing Android versions of their HP12C an other calculators.
