Wonderful calculator - very straightforward to input calculations. Much better than Soulver. Best desktop calculator I've ever used.

I wish I had a dime for every calculator that has been offered for computers.

I have my trusty 23 year old HP-32S always at hand for those quick calculations I can't do in my head.

Magic Number Machine is FREE...

It's strange for me that these two apps have the similar GUI but from two different companies...

It is because the author ceased developing this program (magic-number-machine) and continues to provide downloads including source code.

A new group has taken the program, updated it, changed the name slightly, and is now selling it on the App store.
