Calcrivo
Desktop App

Calcrivo Desktop

A dedicated offline scientific calculator for Windows, macOS and Linux. It uses the same proven maths engine as the Calcrivo website, so results are identical — no internet required.

What the desktop app is not: it is a single dedicated scientific calculator — not the full Calcrivo experience. The complete library of 210+ calculators across finance, health, math, and everyday life lives on the website and requires a browser. Download the desktop app if you need a fast, always-available scientific calculator without opening a browser.
Use it in your browser — free, no install

Or install as a PWA from the browser menu for an app-like experience today — no download required.
