Moffsoft FreeCalc emerges as a practical alternative to the standard Windows calculator, offering a suite of thoughtful enhancements designed to improve user experience. While the built-in Windows calculator serves basic needs, this free productivity software boasts a more robust and customizable environment for everyday computations.

Beyond the basics

Moffsoft FreeCalc takes the familiar functionality of the Windows calculator and elevates it with several user-centric additions. One of its standout features is the adjustable calculator size that allows users to resize the interface to their preference. Its simulated tape for history is also incredibly useful for tracking calculations.

Further enhancing its utility are new keys and a range of practical option settings, including always on top, a tray icon for quick access, and the ability to run on startup. Despite its useful enhancements, its user interface reflects its older design roots, which can feel somewhat dated.

Pros
- Adjustable size and position
- Includes a calculation tape
- Useful new keys and option settings
Cons
- Outdated user interface

Bottom Line

Oldie but goodie

While its visual design is far from cutting-edge, Moffsoft FreeCalc stands out as a highly functional and user-friendly calculator that significantly improves upon the default Windows offering. Its array of thoughtful features, from the comprehensive tape history to the convenient new keys, makes it an excellent daily driver.

Great Calculator - Read the prompts when Installing
djollie111December 6, 2013
Pros
This is a great re-sizeable calculator with on-screen tape. Perfect for using the keypad with. Easy to enlarge, can change color schemes to a few built-in schemes. You can save the tape as a txt file too.
Cons
When downloading from Download.com, be sure to read all the prompts and use CUSTOM install to avoid all the junk CNET tries to stick you with, some of which is questionable. Decline the other software installs, and then you should finally get to the calc install. I don't like how if the calc is already open somewhere in the background it gives you a dialog box and you have to click OK. If it's already open, it should just bring it to the front. Would like some other color schemes, too.
Summary
Great calc for everyday use. Use Custom install to avoid junkware.
download it from Moffsoft website
lincoln904August 17, 2013
Pros
great program. I love having an area I can see the calculations I performed.
Cons
downloading it from cnet.com was a mess. Even though I checked the boxes not to download other software, It did anyway. three or four programs. I attempted to uninstall the other programs before they were installed was the message I received. I got the programs uninstalled but it was a struggle.
Summary
download it from Moffsoft website it comes without a bunch of other programs.
Wanted a calculator... ended up with so much more
fezzer7173February 20, 2013
Pros
It is a calculator and it performs basic math functions.
Cons
I ended up with toolbars, an external file backup program, an adblock program that was - in itself - an ad, and a 4th program that looked like a utility file, but wasn't. I'm kinda peeved that c|net would give a positive review to a software upload that contains potential malware, along with the standard adware and garbage that gunked up my browser ON MY WORK COMPUTER, thanks. Next time, mention that up front, would ya?
Summary
Great calculator, easy to see, use, resize, customize.
manytreezFebruary 14, 2013
Pros
Did everything I wanted in a windows calc replacement and much much more.
Cons
None that I can see.
Summary
Works well
GreenRaven999February 9, 2013
Pros
I just wanted a simple calculator with a tape function, and this one does that. You can also save the tapes.
Cons
I didn't notice any problems.
Summary
Download triggered a security alert.
Dulcimer172January 5, 2013
Pros
Never used the product - see cons
Cons
During the download, my Norton Security Software flagged a "Adware Crossid activity". So once the load completed, I removed the software. This may be nothing. But I will not use anything that has this stigma associated with it, when I can find plenty of other calculators to do the job.
Summary
Better than the standard MS Calculator
Shogun_OneAugust 16, 2012
Pros
Shows you the progression of the calculations like it would be on paper. I find that very helpful.
Cons
I didn't appreciate that it was bundled with other stuff, but you could easily option out of it.
Summary
If you have somehow "lost" your MS Calculator, this is an excellent replacement.
good UI but missing multiply and divide symbol
atshwaMay 2, 2012
Pros
good UI and color options
Cons
missing multiply and divide symbol
Summary
been using for years -- perfect!
Phi1osopherFebruary 3, 2012
Pros
Been using the Moffsoft Free Calculator for years. Each time I buy a new computer or replace a hard drive, this is one of the first programs I re-download. This just your simple, perfectly working calculator with a "virtual paper tape" feature. IF you are at all like me, and susceptible to the occasional wild keystroke, being able to see the "tape" trail as my blazing fingers do their thing is incredibly handy dandy.
Cons
none at all (this box requires a minimum of 10 characters...)
Summary
get it -- its free, and super duper awesome!
It works, it's free & it's got a tape!
webhawk50December 26, 2011
Pros
1. Free 2. Works well & does percentages 3. It's got a running tape
Cons
1. Pretty bland looking; more or less flat 2D-looking but who really cares as long as it works? 2. I would like to be able to enlarge it, but again, this is mere nit-picking
