A pretty good replacement for Mac Calculator app - almost...

My parents really like the Calculator app that comes with the Mac, with one exception: it can’t be resized. They are in their 80s, and would like to be able to have a simple calculator that can be resized so that the display and key numbers appear larger and easier to read.

Well, Resizable Calculator Pro does live up to its name; it’s resizable, and looks almost exactly like the Mac Calculator app. For most folks, it will be a perfect replacement.

My one complaint is that, even when you turn off the Scientific View, the keyboard still contains extra keys not needed for a simple calculator. E.g., e, Pi, EE, mod. It’s the kind of thing that could confuse folks some. (On the other hand, the backspace key and the red Clear key are improvements over the Mac Calculator, I think.). It would be nice if there was a “just like Mac Calculator” View, where the keys where exactly like the Mac calculator. (Again, I realize that this isn’t useful for most folks.)

The other Mac Calculator app feature that is missing is the separate “Show Paper Tape” window, that lets you see what previous calculations were. That is an addition that I think most folks would find very useful.
