This feature proves invaluable, particularly for users who require calculations involving measurements like inches, where extreme precision isn't always necessary.

Good App but.....

It's a good App, it does what it says but when you type the numbers don't make a mistake because you will have to do it all over again. There is no backspace. I give 4 stars.

No other can compare!

I've spent many a dollar on calculator apps trying to find one that I can truly use to satisfy my needs at home and at work. This is the first calculator on the app store that was able to provide that for me. I cannot in good faith recommend any other calculator.

Great little calculator!

Very easy to use and the only app I've found (after 7 or 8 tries) that could divide an inches measurement by a whole number. I was about to give up, but this app saved the day … and will save me lots of time and headaches! Love it!
