Nice, Nag-free, Clean Calculator
FleetwoodCOMarch 2, 2014
Pros
Runs on 10.7-10.9, easy installer, defaults to a simple calculator with option to expand to a full calculator with math, stats, conversions, and expressions
Cons
I can't think of any.
Summary
If you're looking for a good all-around calculator this should fit the bill.

This review was originally posted on VersionTracker.com.<br />I have been looking for and testing every calculator I could find. I almost purchased PCalc, but searched one more just for the heck of it. AM I HAPPY I DID! KoalaCalc is the best I have found, and it is FREE. But, if you like it, consider sending them a donation from the link on their site. I think they deserve something for providing a great application.
Fantastic app

A must have utility - without a doubt

Download this, and throw Apples' thing in the trash. This is a really elegant product. And Macropod are giving it us for free. Nice people.
Really a great product

Summary
This review was originally posted on VersionTracker.com.<br />This calculator is so well done that I no longer keep an actual calculator near my computer as I have done for years. It is nice not to have the extra clutter of a physical calculator, and KoalaCalc is actually more fun to use. Plus it has all the scientific add-ons that I regularly use. Plus, I don't recall ever having a calculator that will add, subtract, mutitple and divide fractions for me and give the result as a reduced fraction. The only small mistake I've seen is the previously referenced approximation to tan 90 rather than just reporting it as undefined. Strange that the atan(tan(90))= -90, for example.
