Numi 3.34 Mac

16 pixels is the default value Numi assigns to an em unit, which tells you something about how it thinks. This calculator accepts a line of text, parses the numbers and operations inside it, and returns an answer without a grid of buttons.

Do arithmetic in plain sentences

Type a calculation the way you would write it in a note, and Numi works it out. It handles percentage math, including subtracting a percentage from a value, and can run several calculations in the same line.

Mix units and formats

The app understands basic CSS units and uses 96 pixels per inch as its default ppi value. Symbolic and alphabetic operations are supported, which makes it useful for quick design or layout math.

Work from the keyboard

Numi runs on Intel 64-bit and Apple Silicon Macs with macOS 10.13 or later. It can integrate with Alfred, and the interface is available in English, Russian, German, Spanish, Italian, Traditional Chinese, Korean, and French.

Speed and system footprint in daily use

Numi opens in roughly a second on an Apple Silicon Mac and settles at around 65 MB of RAM while idle. That number rises modestly during a session with a dozen or so active calculations open, but the app rarely climbs above 120 MB. Dmitry Nikolaev's code avoids background daemons and launch agents, so the calculator contributes zero CPU load when it is not the frontmost window.

iCloud synchronization, introduced in an earlier 3.x release, does not appear to slow local operations. Synced notes transfer between machines within a few seconds, and conflict handling follows a last-write-wins model that matches the way most people use scratchpad calculations.

Time-zone offset parsing got patched

Version 3.34 shipped with fixes for high-contrast display modes and corrected a parsing error that affected expressions mixing time-zone offsets and multiplication. Earlier in the 3.3x line, the developer tightened the Alfred integration so results pass through without a visible window opening, which speeds up workflows that rely on the launcher. The same cycle also brought a revision of the pt and em conversion logic to match the 96 ppi default more consistently across all unit outputs.

A day-rate freelancer's afternoon

A designer quoting a fixed-price landing page needs to work backward from a project fee. She opens a numi download session and types a line that subtracts 18 percent for self-employment tax, divides the remainder by an estimated 14 hours, and adds a 6 percent revision buffer. Numi displays the effective hourly rate on the same line. She then checks the time for a client call by typing 2:30 PM London to São Paulo, and the app returns the correct local time without leaving the keyboard. The entire session runs inside a single window that sits next to her estimate spreadsheet, and the fan on her MacBook Air never spins up. For tasks that involve repeated percentage adjustments and time-zone checks, the text-based approach removes the friction of switching between a separate time converter and a button-based calculator. The numi macos session stays in memory at negligible cost, and all the sums from the afternoon are waiting when she opens the app the next morning.
