Awesome!!
I had the original physical model and this is a faithful experience and I greatly enjoy using it every day. The best calculator by far!! Amazing thank you!!
Thank You
While it doesn't do a couple of things my old 28s does, the extended UI functionality is exceptional.
No other calculator replaces the 28S...I am almost always surrounded by computers and screens, but always reach for this app when maths needs to be done!
Thank you for this effort...if I am ever in EU I will find you and buy you a beer!

I've been looking for a calculator app like this
I only recently discovered this app, so I'm just now digging into its very rich set of features. The Free42 & Plus42 calculators are amazing, but RPN 28x Calc shows what is possible when you ignore the "boundaries" that limit traditional calculators. I can't wait to learn more about this app, and really use it.

No longer miss my 28S
I’m so impressed with this calculator. Thanks for creating this! Great attention to detail on the user interface.
My favorite Calc app and I’ve tried many
I grew up using a real HP32, so perhaps I’m biased towards this interface, but I love using this calculator. It provides the best balance between being a traditional RPN calculator and maximizing the benefits of the smartphone I’ve seen. Most of the straight HP calculator emulators use the original display, which has, at most, 4 visible numbers in the stack. Why? That’s a silly limitation on a smartphone. This app also lets you do actual drag and drop on the stack so you don’t need to be adept at ROLL and ROLLD commands. Bonus binary conversions, etc. Most RPN calcs that aren’t based on an original HP architecture just don’t implement RPN well —including the “new” HP Prime (which I own and don’t consider a traditional HP). I encourage you to skim the manual. This app has so many features that you can get lost. I use, at most, 10% of the features, and would not have found my favorites by randomly pushing buttons.
