Ratings and Reviews
A neat LITTLE thing
Took me a while to discover the RPN calculator because as usual, I open my iPad in Landscape orientation - which does not provide any information or flip button until you go into portrait view. In portrait, one can access the info button and choose the RPN calculator; and one's preferences are retained when reverting to landscape.
It functions well but is very small on my screen regardless of orientation. The useful key click is selectable as ON or OFF but when ON, is very load, requiring volume adjustment of the of the device.
But the bottom line is that it functions properly; it's free; and it has no distractive advertising or pop-up prompts for reviews or upgrading.
So, thankyou, Geoffrey: I'm keeping it. [Just wish it were bigger…] ;-)
