CNET Editors' review
After you get used to how AllerCalc works, you may never use Windows' built-in calculator again. The versatile expression calculator comes with plenty of constants and functions. You can convert among all sorts of metric and English units or set up your own conversions. To enter numerals or symbols, you can use the virtual keypad or your keyboard. The finance box helps you figure out time-based payments. Memory consumption is low at 5MB. The freeware's interface could stand some polishing, though. Some of the function buttons need to be pressed before you type your numerals and expressions, whereas others appear after your input. The help function could be improved by adding sections on syntax and on the built-in constants. The calculator hides in the system tray rather than appearing in the taskbar, and we couldn't get the window to maximize. Still, people who need to perform scientific or engineering calculations will find AllerCalc invaluable, particularly since it's free.
Publisher's Description
From AllerSoft:
AllerCalc (formerly VersaCalc) is a calculator that allows you to directly enter an expression to be evaluated. It features a rolling display storing all your recent inputs and results. More than 40 functions are supported, including algebraic, transcendental, trigonometric, hyperbolic, and financial functions. Also included is a detailed help file containing syntax, usage, and examples for all supported functions. The calculator also provides a list of common physical constants, and it performs various conversions between English and metric units. It supports more than 100 built-in functions, as well as the ability to define your own constants, conversions, functions, and calculations in any numeric base from 2 to 36, and it has the ability to store results in an unlimited number of variables.
This update provides a comprehensive unit converter, improved international support, customizable font and color settings, and an option to minimize to the system tray.

"waste of time"
Version: AllerCalc 2.11
Pros
absolutely nothing
Cons
useless error messages
help function doesn't work
basic functions missing (or in any case impossible to find)
program disappears when you switch to another application and has to be relaunched!!!!!Summary
Somebody has clearly been flooding the site with fake reviews.
This is not an "awesome" product.
I wanted a power function but this calculator only offers squares and cubes. I'll just stick to Excel. -
"has everything but the kitchen skink"
Version: AllerCalc 2.11

"Nice but interferes with many programs."
Version: AllerCalc 2.11
Pros
It has a multi-line display that shows the operations you are doing. You can customize the key colors so you can see them better than the default values (what kind of a retard thought-up light yellow on light grey background?)
Cons
Some of my programs hang or do not start after I have used this program.
Paypal will not allow me to log in when this program is running (OK that's scary!).
I've had to reboot on rare occasions because of problems when it was TSR.
It is possible to load multiple instances of the same program accidentally if you forget it is already loaded.

"fake reviews"

"spectacular replacement for windows calculator!"
Version: AllerCalc 2.11
Pros
First, this calculator features true operator precedence, just like a 'real' store bought calculator (and unlike many of the simple, 4 function calculator downloads here on Cnet.). But there's much more; Allercalc is incredibly flexible, and includes a staggering range of functions and constants. Because it was designed as a teaching tool, you know that it's accurate; and even better, Allercalc is free for personal use (the publisher will accept donations through his website).
The key colors and sizes are completely user changeable, as is the display; so, even if you're vision impaired, you'll be able to use Allercalc. You can select whether you want to focus on finance or science; and you can even design a simpler custom interface, by eliminating unused function keys from the display. The screen shows a record of past calculations, almost as good as a tape display.
Cons
On the minus side, the calculator is not 'skinnable', and the squared off look is a bit dated. The = sign is missing; in it's place is the EXE key, which will confuse occasional calculator users. And the scrolling display isn't as easy to use as a tape display, and will frustrate accountants looking for a paper tape replacement. But these are mere quibbles. AllerCalc deserves - and gets - my highest rating of 5 stars. It's a brilliant calculator, and deserves to be on every computer on the planet. It's that good.

"Not worth downloading"
Version: AllerCalc 2.11
Pros
Lots of buttons
Cons
No manual on how to use it. I've tried to use it as a financial calculator. I couldn't calculate anything except the PV on financial box. There was no instruction on how to use the calculator (not even on help option). Not worth downloading.

"Trojan Warning"

The setup program is classified as the trojan horse TR/Sleeper.D from the antivirus program avira
