Reviews: What People Think About RPN Anywhere

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.

It takes some practice but it works well once you get used to it

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!
