The only calculator you need

This calculator app has everything and is extremely configurable. I have been using this App since it first came out (before they used the term app), and I’ve never been sorry. James Thomson is an extremely conscientious programmer and is very receptive to suggestions and bug reports. It’s nice to have the same calculator on my iPhone and Mac.

FWIW, another great app by James is DragThing, which I use on a regular basis.
