Active RPN Calculator Reviews

Best RPN Calculator

Now with the addition of key clicks, Active RPN 1.2 is simply the best designed and functional RPN calculators for the iPhone and iPod Touch. Keys are large and key labels are easy to read. The support site is excellent and the available instructional videos are great for teaching those new to RPN calculators.

Delightful

I have MathUPro RPN calculator but I wanted something uncluttered for basic calculations. This perfectly fits the bill. Despite its simple appearance this has some nifty features including programming, stack display, recent operation display and able to look back at a list of calculations (Text LIst). Nice to be able to have the keys emit no sound vs click vs tone.

Replaces an HP calculator

I have owned an RPN HP calculator for umpteen years. My colleague owned one, but hers broke, and she said HP doesn't make them anymore. When I discovered Active RPN Calculator I downloaded it. It is as good (in someways better) than my HP, so I gave the latter to my colleague. Two peoiple are happy.

Lucky that you found this one !

I tried many other rpn calc. apps. All have some kinda wiz bang. Only this one had BOTH buttons. 1) Last X 2) Back space ( for fat fingers lol)

Very nice little app. I can still have my HP-style RPN calculator with me all the time. A great bargain for the price.

Best RPN calculator yet!

Fast and responsive without lags in data entry or calculations. Simple, good looking interface has some of the old HP style, without trying to be an exact replica. If you don't need the more esoteric functions most of the time, they can be hidden for a cleaner appearance. Animation of the stack is a nice touch. Good work, but can you make the icon look as nice as the rest of the app? The current one is ugly, IMO. Also, how about a retina display update for iPhone 4?!

Awesome, fast, clean, just right!

I'm glad I looked for an updated RPN app to replace the laggy i48 app I have been using for the past 3 years. This has a much clearer interface, is faster, and has a dual display. Great! Would have paid!!

Absolutely Awesome

PLEASE UPDATE FOR iPhone 5 AND RETINA!!!! I love this calculator, and its an absolute steal at .99 cents. The developer could easily charge $2.99 for it. If RPN is your thing this app is fantastic. If you are just interested in checking out what RPN and programmable calculators are capable of then this is also for you.

Great pocket alternative to HP48

I can't even work a "regular" calculator, so this app is great for me when I'm away from my desk and want to make a quick calculation - everything from price comparisons at the grocery store to trig calcs on the shop floor.

Finally an everyday RPN calculator!

I don't need an engineering calc but I do like RPN. This app is just what the doctor ordered and it is well implemented.
