steve-of-indiana ,

I am an old RPN guy so I use another calculator for my personal use but found this when someone I know asked me to find them a calculator for them.



The only changes I would make (these may be things that I simply do know how to fix in a Settings menu someplace)



1) in portrait mode there is a black bar at the bottom of screen

2) there does not seem to be a way to zoom in on the calculator



I am using a recent iPad (non-Pro) with the current version of iPadOS & have not noticed any crashing or issues other than what I have mentioned but at almost 70 years of age my eyesight is not what it once was so bigger is better.
