Calculator

A Windows 11 calculator rebuilt from scratch — five modes, thirteen unit converters, and eight surface themes. Portable, 2.4 MB, nothing to install.

Download for Windows Version 1.1.0 · 64-bit · ZIP, 1.2 MB

Installed copies update themselves — this download is only for a first install or a new machine.

What changed in 1.1.0

First self-updating build. The app now checks this page on launch and can update itself without a reinstall — only the 167 KB resource bundle is downloaded, not the executable. Themes also moved into the hamburger menu, under a Themes section.

Running it

  1. Unzip anywhere. Keep Calculator.exe and resources.neu together in the same folder.
  2. Double-click Calculator.exe. The build is unsigned, so Windows SmartScreen asks once — choose More info → Run anyway.
  3. To pin it, right-click the exe and choose Pin to Start. A shortcut can live anywhere; the two files must stay side by side.

Windows 10 1809 or later, 64-bit. Uses the Edge WebView2 runtime that ships with Windows 11. Nothing is written to the registry — delete the folder to remove it.
