Great program!
This is a great RPN app! It works very well and the developer support is exemplary! I had an issue with iOS 11 update and the response to my inquiry was swift and simple. Way more than I’d expected for a $6.00 application. Others should emulate this fine example! Well done Mr. Brock, thank you.

Great rpn calculator
Couldn’t do without it
RPN Rules
RPN rules and this is the calculator to do the job
Had it since the original. Use it. Love it.
This has been one of my most used apps over the years. It's had very few if any updates - because it hasn't needed them, until this latest OS release. I was sad to see a notification that this RPN calc wouldn't work anymore. I'm now happy that this new updated version came out.
My only suggestions are to make the stack longer and to add 'mils' in the conversions.

Must have RPN
I grew up using RPN, and have no interest in ever learning algebraic entry, so this app is a lifesaver.
Love it
Excellent app. So convenient. I don't have to carry my HP17 anymore
Nice RPN calculator.
This has my "go to" calculator for years. The new version is nice improvement,
Love it
This calculator is a real buy at this price. I love all the choices and the ability to get foreign currency quotes. I used to use RPN notation and then lost my HP calculator. This machine is really slick. I couldn't live without it.
It's like having my HP back in my hand
Live it. RON logic is the way to go.
Comprehensive and easy to use
Have been using RPN calculators since mid 70's. This is thorough, seems complete, straight forward, logical, and easy to use.
