Great calculator with one odd interface issue
I use this calculator for complex number calcs all the time but there’s one gotcha for a new user. It’s not obvious how to enter a number in polar format. To do so use the angle key to get it into polar display mode and then the ‘i’ key is used to enter the angle.
Why does the app mute other apps?
When playing music or listening to a podcast, when you use the calculator it mutes the music. Why?
This must be fixed. I’m looking for another rpn calculator that doesn’t do this?
Fix it please

Good RPN
This app is great! I have been using this app for years as a clean and simple, RPN scientific calculator. I was surprised to see the recent update to SwiftUI. On one hand, the update adds some great functionality, like the ability to turn the click sound from the key press off, maculate how the numbers are displayed, and let's you see the stack. On the other hand, SwiftUI is just downright fugly. There's no other way to say it. It really stinks. That isn't this developer's fault, it's Apple's. What makes it ugly is that there's too much border, or white space, around the buttons. IT's true for every other app I've seen migrated to SwiftUI. They all get ugly and harder to use.

Update to SwiftUI has slow entries
The calculator keyboard responds very slowly with this update. I can type 4-5 numbers before the first number appears.
Very annoying and difficult to see if one has made a mistake on entry until a few seconds later.
I am using an iPhone 14 Pro Max.

Cool little Calculator
Works well on MacOS
Found a fault
When an imaginary number like X=j1.837526E18 is entered X^2[X] is correct but X^3 is not.
Best
This app works a treat. Been using it for years. Don’t be put off by advice that it no longer functions.
Gloss black and genuinely free!
• RPN with complex numbers.
• A tiny app requiring next to no space.
• Very fast - but please see below!
• Completely devoid of silly banners and advertising.
• Highly polished appearance which suggests the developer enjoys symmetry!
Unfortunately, the need to scrutinise miniature graphics in an unusual layout leads to unintuitive, clunky operation.

Free, simple, functional, no ads or in-app purchases. Awesome.
So far so good on iPhone SE.
Good RPN Calculator
The design is clean and it’s RPN. It would be nice if it showed the stack but that’s my only quibble.
Calculator doesn’t work
This no longer works with the latest iOS software. I paid good money which is now lost!
RPN!
RPN! Need I say any more?
Best iPhone 6 free RPN calculator
Sweet little app for both portait and landscape HP calculator fans!
Fonts on iPad
I recently installed the latest version (1.2 ?) and on the iPad 2, the labels on the buttons are now using an underlined small Helvetica font. As a result, many of them are unreadable. The previous version used a much better font. It would be nice if the app allowed enlarging the fonts for old people like me with vision issues. Would give this app 5 stars if the fonts were fixed.

Great app
Excelente
Excelente aplicación aunque esta ultima actualización se tardó años en llegar no importa ya que funciona de maravilla con o sin actualizaciones
Get the PRO version
Coddington has a PRO version of his RPN calculator app that works fine on iOS 9. It does not show both of the functions at the same time for keys that do double duty like the regular version did (for example X squared and square root of X), but at least it doesn't crash and doesn't have the annoying upside down "feature". For the second function keys, just type the 2nd key in the bottom left corner, and the entire keyboard now shows them.
Hope the developer updates the app to adjust the PRO version to look more like the regular version keyboard, as the Pro keyboard has an odd look to it.

Marvelous - solves sad fact of consumer rejection of RPN
...but it has stopped working in latest iOS!
We have no right to expect updates to freeware, but we can hope and pray for what we don't deserve.
