Description of RPN 30

Reverse Polish Notation ("RPN") is an alternative way to complete calculations. Many find it to be more intuitive and user-friendly than the "normal" way of using a calculator. RPN works entering numbers first and then the operator (i.e. 53 47 + will give you 53 + 47 = 100). This is my artistic interpretation of the ideal form for a calculator, taking inspiration from the standard Apple iPhone calculator. Make sure to spend a few minutes to get the hang of the calculator and also read the short help guide (accessed by a long press on the help button) to get the most out of it. No ads, no paid features, always free to use. Please enjoy and leave a review if you like the calculator.

  • Love the streamlined operation

    Big buttons and smooth navigation across the pages. You should apply your talents to make a better (similar) Watch experience. All too crowded and clunky.
  • Need improvements

    I’ve been using a physical 42S and emulator on my phone for years. The down side is that the keys and display font are small. Apple default calculator app, on the other hand, have very large font and large key size, but it’s not RPN. This calculator here has the potential to be a great alternative to both, but it’s not (yet).

    1. Stack display is a bit confusing. Took me a while to figure out Y is on top left corner, and then the next 3 levels up on the right. It would be more consistent if you skip the top left corner position, and just have the stack on the right.
    2. While alternate functions are activated by long pressing the number keys/layer, in the advanced function keys/layer, it requires pressing ALT then another key. Why the different behavior?
    3. Store/recall does not work at all.

  • Huh???

    I agree with Talasoft guy. I went through engineering school using an HP 15 C calculator. I found this calculator too confusing to use. The developer might want to consider that people looking for an RPN calculator app are those of us who are familiar with RPN and don’t want to carry around a calculator anymore. In other words don’t alienate the people who are most likely to use your app. Furthermore, I am not sure anyone trying to learn RPN will make any sense to what’s happening on this calculator.
