Brilliant Calculator
Fantastic calculator for my day-to-day math needs. For years. If you’re accustomed to RPN, require a visual stack size of 10, and all the requisite math functionality, this is a superior calculator app. Big thanks for putting it together.
Fantastic app
Best calculator app I’ve found! Thank you.
Reminds me of my old HP
This is one of my most used apps. I love it.
Long Time RPN User
I’ve paid a lot of money over the last 30 years for various HP RPN calculators. Some turned out to be collectors items. This is as good or better than those.
RPN Heaven
I retired my HP35 when I got this app. It’s so much more efficient doing complex calculations. Love it!
Very useful
It's convenient to have most of the everyday functions of the hp48 with some added features (like more visible stack, bigger keys, undo, ....).
My favorite RPN app.

Very Good hp 48/49 Emulator
All self respecting engineering school students used the hp (real hp before Compaq merger) 48 and swan song 49 handheld calculators. I am amazed how tell this emulates it. With today’s dollars the real calculators sold for roughy $4k.
Goldilocks RPN
This calculator is just the right mix of features/functions from the wonderful 48 series machine. For those fortunate enough to have learned RPN, you can relive that experience every time you are greeted by a need for computation.
My Go-To Calculator!!!!
This app is so good that I almost don’t miss my old 48. The haptic feedback upgrade was a great addition. Love that this still works on IOS18.2.
Fantastic calculator
This is my go to calculator, and the best RPN calculator app I’ve tried.
Just works!
Grew up using RPN calculators and this one works well without any fuss. I’ve used this calculator for years now and use it for any hand calculations I need.
Best RPN Calculator
I've been using this app for a few years across a couple phones now and it's still the best one I've tried. Well worth the money. Fully functional no-frills interface that works smoothly.
This is my main calculator for work and home (engineering work, quick calculations that don't warrant writing a script or cracking open matlab)

Great HP48 Reimagined
This is the best HP48 RPN style calculator for iOS. Highly recommended if you love RPN and the venerable 48.
Best RPN iOS calculator
I’ve tried several free versions. I read the reviews and figured this one was worth the $4 risk.
No jankyness / bad UI. Mimics my old 48GX pretty well (minus the graphing features). Everything works as expected!
I don’t mind paying for software, especially if it motivates the developer to continue porting the app to each iOS release— (historically, a lot of my freeware apps have lost modern iOS support whenever Apple deprecates an old feature.)

Suits my needs perfectly. RPN is versatile and your implementation is superb.
Nice
Good for quick calculations. Wish it had scrolling stack but otherwise nice.
Amazing RPN calculator
Very easy to use, super fast clean interface, good layout, no ads.
I love the simplicity and speed, I tried multiple other RPN calculators from the App Store and this one was the best, I have been using it for years and I love it, it just works.

As advertised
Excellent, simple call back to the HP 48 for people who like to do arithmetic RPN style.
Très bonne app
Une calculatrice ´HP’ simple et efficace avec un écran très pratique (contenu de la pile affiché)
Best RPN app
Having gotten used to RPN, I love that this app provides me the basic operations needed for my daily calculations. RPN is a definite logical method and this app provides 👍
