Soulver 3 — Mac download

Soulver 3.16.3 runs on any Mac with macOS 13.5 or later, on both Apple Silicon and Intel processors. It is an original notepad calculator built for day-to-day math problems. You type calculations in plain text, and Soulver gives instant answers for any numbers it finds.

Live totals and instant unit conversion

• Quick estimates — type a list of costs with commas and labels; the total appears live.
• Unit conversion — add units like "25 CAD in EUR" or "14 ft in m" and Soulver converts them, including live currency and cryptocurrency rates.
• Small calculation documents — use linked line mode to reference previous answers, and organize work with headings and comments.
• Reusable logic — define variables with auto-completion, then reuse them across lines.
• Calculations from anywhere — highlight text in another app and trigger the macOS Services action or an Automator workflow to get a result without leaving what you're doing.

Operator spacing and the macOS 13.5 cutoff

• The app formats numbers with spaces around operators and thousands separators.
• It requires macOS 13.5 or later.

Three pre-flight tweaks for your first sheet

Open Soulver 3 > Settings and make these three adjustments before your first real sheet.

• Number formatting — under General, switch thousands separators on or off to match how you read figures. Turn off “spaces around operators” if you prefer tighter notation.
• Syntax highlighting — go to Appearance and pick a colour scheme you can scan quickly. The default is fine, but the low-contrast grey for comments can disappear on some displays.
• Currency defaults — under Live Currency, set your home currency and a handful of secondary currencies you actually use. Soulver fetches rates once per session, so prune the list to what matters.

A freelance translator’s afternoon

A translator working across three clients uses Soulver 3 as a scratchpad that handles invoice math, deadline checks, and rate comparisons in one window.

She types a few lines:

• Article: 2 450 words at 0.12 CAD/word
• Proof: 3 pages at 45 CAD
• Rush fee: 15% on Article
• Total CAD
• Total EUR

Soulver tallies the project total, applies the rush percentage to the article line, and converts the final amount to euros using the live rate. On the next line she checks a deadline — March 17 + 4 business days — and gets the delivery date without opening a calendar. She saves the sheet to a client folder in the sidebar and moves on.

• macOS 13.5 or later
