Best one
Does it all, excellent interface and operations

I like this implementation of RPN. Would be nice if there were a native iPad version — that somehow took advantage of the larger screen.
Hp-12c +++++
For those of us who grew up using Reverse Polish Notation, RPN is built into our hand. This little calculator app is easy to use, and has many more features than the HP-12C. Weight and volume conversion is often really useful, and it's easy here. Currency conversion! Get updated conversion rates with a couple taps. I've been using this great app for about 7 generations of iPhones.

allRPNCalc is best one out there
I've tried most of the HP calcs for iphone. This is the most intuitive interface and includes super helpful conversions, including currencies. Love it. Thanks for updating!!
Works great, except
I’ve been using this app for many years and find it great as a financial and general calculator. I calculate loan payments routinely. It has always worked great. However , recently I looked at an amortization chart and could not exit the chart. Stopping and restarting the app did not clear it. I had to restart iOS to get back to the main page. Please fix!

Response from developer
Charlie- To get out of the Amort Table just touch the Done button in the lower left corner of the display. To learn how to use the Amort Table, touch the ? key followed by the Amort Table key. If you think there is still a problem, please contact me directly. Touch the circle i icon in the left side of the display, then touch the About tab and select the "Contact tech support" button and send me the details. I hope this helps. Sincerely, Ernie Brock Developer
allRPNCalc - the best
I have bought very few apps for my phone. The purchase of allRPNCalc is the exception. I spent a few dollars on this several years ago and it is the best use of money for an accessory ever. A powerful RPN calculator, that does everything I need and more. It is regularly updated to keep it in sync with all the updates iOS undergoes. I highly recommend this app to anyone that needs an RPN calculator. You will not find better.

Great RPN calculator
I use it all the time!
Great RPN calculator!
I used to work for the HP calculator division that pioneered RPN. Trust me. This is beyond a full featured RPN machine. Well thought out. Great job!
Each version is even better than last. Now at v4.1. Very happy customer.

Excellent
Been using for years. All the functionality plus more. Never a crash.
Great RPN Calc!
Calculations are spot-on and this developer has been kind enough to provide free updates for many years now... Which makes it well worth buying. I've tried others and I still like this one the best. Very easy to use yet it has the depth and breadth you'd expect. I use it frequently for mortgage calculations and amortizations.
