Soulver overview

Soulver helps you do quick calculations and work things out. It's quicker to use than a spreadsheet, and smarter and clearer than a traditional calculator. You type out your problems as you would on paper, and Soulver calculates your answer as you type. You can do calculations over multiple lines, and use words alongside your numbers so they make sense. Soulver is great for adding things up, easily doing percentages, and converting things, like currencies.

Use Soulver to play around with numbers, do "back of the envelope" quick calculations, and solve day-to-day problems.

What's new in version 3.16

Calculator

Screen Density Calculations

Added PPI/DPI units.
Convert between physical length and pixels at a given density, for example `1 cm in px @ 326 ppi` or `40 px to cm at 96 dpi`.
Added a screen density function like `ppi of a 15" screen at 1024x768`.

Trigonometry

Added cotangent and cosecant trigonometry functions (cot, csc) and their hyperbolic, inverse, and degree variants (Coth, csch, acot, acsc, cotd, cscd, acotd, and acscd).

Units

Added rates for the Uniswap (UNI) cryptocurrency.

Functions

Added an "is x prime" function: "is 59 prime" (= true).

Statistics

Added standard deviation: "standard deviation of 20, 30 and 40" (=10).
Added "avg" as a synonym for "average" ("avg of 3,4,5").

Calendar and Time Zone Calculations

Added a shorthand time difference function: "time difference Paris" [interpreted as "what is the time difference between here and Paris"], plus "time diff paris" and "diff paris".
Added a "years to" function (years to 2029).

Percentage Phrases

Percentage phrases now support arbitrary comment words in more cases. For example:

20% discount off $500
5% gratuity on $95

US customary units are now returned in certain cases when the input uses US customary units.

Calculator Bug Fixes

Fixed an issue with rounding functions and lap times (thanks Jasper).
Fixed an issue with line dp settings not applying to feet and inches (thanks Jon).
Fixed an issue with locales that use a dot as a decimal separator and a space as the thousands separator (though uncommon, this can be set as a custom locale in macOS system settings).
Fixed an issue with adding clock-formatted times around daylight savings change boundaries.

Languages

Added Japanese, Korean, and Italian localizations.
Soulver's documentation is now translated into all languages.

General

Minor improvements to the Calculator settings window.

Version: 2.6.7

This is where the Apple App Store really irks me. I have the App Store version of Soulver and its crashing on launch. The App has been updated to version 2.6.7 but not on the App Store. I’m left with a crashing app because I can't update my version. This has become beyond tedious.

2.6.4

Version: 2.6.4

Been using this a 2-3 times a month for two years. Replaces simple spreadsheet calculations, and it is a joy to use. Bulletproof. The UI is a little threadbare but it is still perfectly usable. I would miss this app if it were gone.
