A free Soulver Alternative for quick sums

Soulver is a natural-language calculator built as a notepad: an answer column beside your text, line references, variables, units, dates and live currency, stock and weather data, synced over iCloud. It costs $59 once, with a 60-day trial, and needs macOS 14. Notchy's Calculator tab is not trying to be that. It is the scratchpad for a quick sum, one hover away in the notch, free, from macOS 13.

Why use Notchy instead of Soulver?

  • Answers as you type

    Type an expression and the result updates live. Press return to commit it and copy it to the clipboard — no keypad to click.

  • History that survives

    The lines you ran stay in the tab after the notch closes and after a relaunch, and the last answer carries into the next expression.

  • Where Soulver is in another league

    Variables, line references, subtotals, unit and currency conversion, date maths, tags, iCloud sync and export. Notchy's calculator does none of that. If you plan budgets or work through calculations in prose, Soulver is worth its price.
