The Fraction Calculator feels and behaves exactly like a calculator with one exception, you're working with fractions. So now when homework (checking of course) calls for fractions, or your carpentry project needs you to add eighths and sixteenths dozens of times, or maybe you just want to be able to recalculate that dinner recipe to accommodate for five rather than two – turn to the Fraction Calculator.

Fraction Calculator allows for adding, subtracting, multiplying and dividing both positive and negative fractions, displaying the results both as a fraction and a decimal. There are also functions to allow for simplifying, reciprocals, squares and square roots.

Fraction Calculator Supports the Touch Bar on the MacBook Pro, and is fully VoiceOver accessible.

For Fraction Calculations it's the Best

Working with wood and imperial numbers is a real pain in the app -- but this program is a very simple lifesaver. The only problem is that there's no "welcome screen" that explains how to use it. Here's how:
- if you're inputting 2 3/4 (for example) you click the "2" in the green area, the "3" in the purple area, and the "4" in the blue area -- then you can hit " " or whatever operation you need.

there are better reviewed calculators but if you're really trying to deal with fractions this is the bomb.

suggestion to the developer: have a "how?" button on the app (maybe to the right of the stoplights) that explains what I just wrote above and also has a link to launch your email for further questions. also, I was trying to use it by typing on a keyboard and that did not work (it made 4 1/2 into 42/2 (division operation). maybe make "command /" into the fraction operator? so I could type 4 space 1 command / 2 to input "4 1/2"? (if you do that, add it to the "how?" instructions

Great calculator for woodworkers

I often need to add a variety of different fractions when building cabinets and this app makes this task super simple. Would be great if I could see all the dimension I had entered so I can verifiy I entered them correctly versus what I do now which is add the dimension several times to verify I get the same result.

WOW! This is great. I wish other calculators where as well thought out.

This is extremely easy to use.

The calculator’s window is resizable
making it very easy to read.
The three keypads are great.

This is my favorite calculator.

I wish my other calculators had
resizable windows and where as
thoughtfully layed out.
