RPN Anywhere Reviews
Great app if you prefer R.P.N. But…
Have been using this app for several years and it is my go to calculator. But one thing is missing. Can you please add a number storage for number recall? Like a memory 1 and Memory 2 button. The stack is great not often I want to perform several different operations on the same number.
Bugs
Copy accumulator (X) doesn’t seem to work. V5.1, Ios 15.5, iPhone 8 Copy All doesn’t seem to work Cut will delete, but doesn’t put the number on the clipboard Paste doesn’t seem to work
Great RPN Calculator!
If you're looking for a simple RPN calc that features keyboard input that makes sense (and/of is customizable) compared to the default calculator (in RPN mode) then get this calc. The only things I wish it had are a few more GUI keys. An EE key in "basic" mode would be nice, and more stack control keys (Roll up/down, Drop) in both modes for when you want to be lazy and only use the mouse. The "scientific" mode already features an EE key and thanks to the programming function I added the stack control keys as programs. Programs appear as keys below the display starting at the left, I added a couple blank programs with spaces for titles to move my stack control keys above the numeric keys. It's almost perfect!
A waste of time and money
Copy, paste are broken. No instructions or many. Unbelievably bad app.
Best practical programmable RPN iOS calculator
Though I am eager to give this app 5 stars, I bought this for use on my Series5 watch but find that there is a bug with WatchOS 7.1 which won't let me swipe to get back to main from the function screens. Unfortunately, the app support page is not in English, so I don't know if there's a workaround. So why did I give it 4 stars even though it has a debilitating bug? It is unapologetically RPN. The layout and functionality isn't perfect; but it is the most practical design I have seen for writing useful scientific/engineering programs on an iOS device. The layout and functionality on an iPad is stellar. I will definitely keep this app hoping that the watch bug gets fixed. It is very much worth it's price.
bug report - apple watch:
Arc tan does not appear to work. Need this fixed asap. Trig functions are the only reason I purchased this app.
Bug report
App reports 3.17^(1/36)=4.89e163. Correct answer is ~1.0326. This error occurs for all 3 page #1 functions: X^y, Y^x or Yth root X. Occurs on iPhone and watch. Interestingly 30.91^(1/36)=1.1 correct! One quirk: Swipe up brings up the extensive operators pages with buttons to select between #1, #2 or PRGM but then you are stuck there... until you notice that only a “short” down swipe and not from top of screen, but center or bottom third gets you back to the main screen. This is my first really useful calculator for the Apple Watch!
Full featured app
It takes some practice but it works well once you get used to it
