Customer Reviews

Great App

The best apps are simple. This little beauty uses very little screen space and tracks your work as you go. I highly recommend it over the dashboard calculator that comes with OS X. Great idea and great execution.

My Favorite Calculator

This little app is great. I've been using it for years before the App Store existed. It is one of my must have apps for each new laptop I setup.

Serves its Purpose

Very good calculator for basic scientific functions. You can copy/paste results if you need them in your next calculation. Clean interface.

Some drawbacks:
- trigonometric functions only return values in radians
- cannot store answers in variables, and no M+/M- functions
- decimals cannot be converted into fractions
