Soulver 3 Review | Macworld



Calculations are for computers, but Soulver makes them human again. The revised version 3 app lets you enter readable and formatted arithmetic metrics, features, dates, and device conversions, and get results you can use.

It is especially useful if you are constantly working among combinations of devices, such as throughput over time (Mbps per hour), or often return to the same metrics that you connect to different values.

Soulver handles conversions and metrics written almost as we speak them.

Soulver is not a calculator as such, even though it tackles any math you write on it, no matter how long the operating set. (If you want a calculator, try PCalc.) Rather, it is a way to work comfortably in a math and device environment to calculate problems that are often needed in daily life.

You can use variables to create different scenarios with the same number, track sales and commissions, or calculate complicated volume numbers without having to build a spreadsheet. Text formatting options and comments let you keep everything readable and self-documented.

For example, instead of figuring out the calculator approximation to a percentage, you can often require a specific sequence to hit the% button, enter into Soulver, 20% of $ 1

2.11 and become immediately presented for $ 0.61 .

And I don't know about you, but when I use a recipe for imperial measurements, make sure I get teaspoons, tablespoons and cups right when I double or halve? I'd rather write 8 pp in cups in Soulver and find out the answer (half a cup). If you need custom devices, you can also add them.

Soulver divides vertically: calculations and statements are displayed on the left and results on the right. You can enter a wide variety of maths and conversions, which include simple calculations with parentheses and the order of priority, which you may remember from math classes: (2.5 + 7.5) * 1.11 / 10 - 15 ^ 2 . (It is -223.89 by the way.)

The revised version also offers several ways to get results by entering something similar to regular speech while still being consistent with a structure, so you can hunting for an answer through contexts of existing numbers.

A unique slider over slider allows you to "scrub" through numbers to see results, so you can quickly run through many options without typing. Although not recommended for political decision-making, it can be helpful when adjusting the sizes of a hanging wall or how many miles a day to drive for a walk.

New in version 3 are two features that require close adherence to syntax than most others in the app. A "rule of three" feature where Soulver can fill in the form. This is good for proportions. You specify one of these in the form "number is to number as numbers are to what," which in 9 is to 16 which 27 is to what (answer: 48).

With dates, you cannot enter arbitrary calculations, as Soulver relies on an Apple math library for dates. But you can find many results that would otherwise involve manually counting days or weeks on a calculator. June 1, 2019 - 6 weeks gives you, for example, April 20.

Date and time calculations have some limits, but turn when you look at a calendar and trust your fingers.

A common problem for us transmitting large files over networks and the internet is getting a decent estimate of how long it will take to copy these items or the capacity of my throughput. I regularly approach Soulver for this as it accepts calculations such as:
