### 3/5 — Portrait only…

*2022-02-07*

This is a nice little RPN calculator with an unusual, permanent display of the stack.

Unfortunately, it is not suited to using an iPad in landscape mode because it does not rotate. I'd also prefer more precision than just three decimals.

However, anyone happy to use portrait display all the time will enjoy its clear layout and easy to read numerals; and because there are no interruptions for advertising or other distractions, it's immediately on hand and very fast.
