Customer Reviews

Totally meets my needs

I have no need for a calculator capable of performing high-level mathematical functions, as this app does. I regularly only carry out simple calculations. Thus, this app more than meets my needs. The additional functionality does not overpower the interface screen.

Pro: It keeps a running tally in a window on the right, a handy feature.

Con: Once in awhile, the app closes out randomly in the middle of a calculation and needs to be re-started.

Calculator app

If you need a calculator app you really can't go wrong with this. The program is simple to use and very intuitive. If you are looking for a good calculator program, your search is over. The only reason I gave this a 5 star rating is because there was no 6 star rating as an option.


Accepts key input in logical brain-guided order - would say that this calculator will serve home-finance controllers, accountants, and financial and scientific users. Has a "tape print-out" when required, and has been updated to work with Apple's new split-screen feature - which is extremely useful.
