Soulver: The English Calculator
Face it. As students, we’re bound to be working in the middle of the night on that almost-forgotten homework assignment. If you’re doing stuff that could (somehow) change the future, you don’t want to use a standard, dull calculator.
Moreover, I’m guessing you’ve had enough math today and just want to get this over and done with. What could you do? Let me introduce Soulver, the calculator based on the English language.
From the makers of Picturesque, Soulver comes a very simple and intuitive user interface. You type whatever you want to find on the left-hand plane; once the computer figures out the correct answer, you get the result on the right. Soulver automatically updates and calculates when you type, so there’s no enter button or “equals” key that needs to be pressed.

Instead of typing numbers and signs, Soulver uses English phrases. Instead of typing “3×5″ or “100×0.2″ you can write “3 times 5†or “what is 20% of 100â€. Soulver also uses variables. For instance, if you defined “x” as 200, you could say “456 times x†and Soulver will give you the correct answer. Though you can still type mathematical phrases if need be.
Soulver may be easy to use, but it is also very powerful. Clicking on the Answer Palette toolbar icon brings up a dashboard with multiple answers to common questions like “What’s the square root?†or “What’s that as a fraction?â€. Soulver can also calculate whatever number you’d like to the 100th decimal point in real time just by dragging a slider.
Soulver is packed with many scientific and algebraic features, yet is still as easy as working in a word processor. Soulver is available with a price tag of $17.95(USD), however, you can use it for 15 days to see if it’s the solution to your mathematical woes.


Unfortunately, even though it uses English phrases it appears it gets some stuff wrong. 10% of 45 is not 5, it is 4.5 (one of the screen shots shows this).
I noticed that too, Adam. Either it’s rounding up (which I would hope there’s an option for auto-rounding) or it’s just wrong, I’m guessing the former. Cool app though, definitely one to mess around with.
