# Numi

> Text-based calculator for Mac with unit and currency conversion

Numi is a calculator for Mac that mixes math with plain text: you write an expression in words or symbols on a line and it returns the result. It converts currencies, units and time zones, supports variables and running totals, and can be extended with JavaScript plugins. The Mac app is the main version; a Windows build is offered as a preview and a terminal version runs on macOS and Linux.

## Key features

- **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.

## Good for

- 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

## Worth knowing

- 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.
