Numi vs Soulver

Numi

• Mac users doing quick sums with currencies, units or percentages
• Keeping a running calculation with labels and comments beside the numbers
• Buyers who prefer a one-time license to a subscription

Soulver

• Working through multi-step sums with notes beside the numbers
• People with a Mac, iPad and iPhone who want one purchase for all three
• Trip budgets, quotes and split expenses that mix dates, currencies and totals

Numi

• The Windows build is labelled a preview and the Linux desktop app is listed as coming soon; on Linux only the terminal version is available.
• The terminal version does not yet support dates, time zone conversion, variables, plugins or the sum, prev and avg tokens.
• Unlimited notes and iCloud sync need the paid license, and the changelog says creating a new note requires activation.
• The buy page shows no price before checkout; $29.99 is the US price from the Paddle checkout that the Buy button opens.

Soulver

• Apple platforms only: it requires macOS 14, iPadOS 17 or iOS 17 or later, and the site lists no Windows, Android or web version.
• There is no free plan. After the 60-day trial, sheets can still be viewed and exported, but creating and editing them requires a purchase.
• Access to 150k+ stocks, Wolfram|Alpha queries and advanced weather data costs a separate $26 a year on the App Store.
• Major versions are paid upgrades, which the vendor says have averaged seven years apart; Soulver 3 owners get Soulver 4 at half price.

Numi

Calculations written as text

Type an expression in words or symbols, such as a dollar amount in euros minus a percentage discount, and Numi answers it. Word operators such as plus, times and divide by work alongside signs.

Currency and unit conversion

Converts currencies by ISO code, name or sign, with rates updated several times a day, plus cryptocurrencies and units of length, area, volume, weight, temperature, data and CSS.

Time zones and dates

Shows the current time for a city or time zone, converts a given time from one zone to another, and handles date arithmetic such as today plus two weeks.

Variables, sums and averages

Values can be assigned to variables and reused on later lines. The prev token refers to the previous line's result, and sum and average work on the lines above.

JavaScript plugins

Extensions written in JavaScript add global variables, custom units and custom functions. The documentation says only a limited part of the API is exposed so far.

Terminal version and Alfred workflow

A command-line version, numi-cli, installs on macOS and Linux, and an Alfred workflow built on it answers expressions typed into the launcher.

Soulver

Answer column

A sheet works like a notepad: write words and numbers on a line and the answer appears alongside it as you type, with a floating total for the whole sheet at the bottom.

Line references, variables and subtotals

An answer can be referenced on later lines and updates when earlier lines change. Multi-word variables, subtotals and totals of every line carrying a tag are supported.

Currencies, units and dates

Recognizes 190 currencies, more than 200 units, percentages, calendar and clock-time math and time zones, with functions for sales tax, loans, interest and inflation.

Live data

Pulls live and historical currency and stock prices and weather into a sheet. Access to 150k+ stocks and inline Wolfram|Alpha queries needs the optional data services subscription.

iCloud sync and export

Sheets sync through iCloud across Mac, iPad and iPhone with automatic backups. They are plain text and can be exported to PDF, printed or sent as a styled HTML email.

Automation and command line

A Shortcuts action, URL schemes, macOS Services and an Alfred workflow connect Soulver to other tools. A free standalone command-line tool can create and edit sheets.
