Calculator Fun: one Windows app for math, conversion, and quick practice

Calculator Fun is a full-featured Windows desktop app built with a Sciter-based UI and a native C++ host. It is meant for anyone who wants more than a basic calculator without installing a heavy suite.

What you get in one window

• Scientific calculator with memory, roots, powers, logs, trig, and keyboard-friendly input
• Unit converter across practical categories (length, mass, temperature, speed, time, and more)
• Calculation history so you can review recent work without losing context
• Mini-games (guess number, quick math, tic-tac-toe, and others) for practice and breaks
• Settings for theme, angle mode, decimal places, and hints

Who it is for

Students, homework sessions, and everyday number work benefit from having math, conversion, and light practice in a single offline-friendly app. If you only need a tiny four-function tool, this might be more than you need—but if you like one place for serious math and quick learning games, it is a strong fit.

Distribution uses a standard Inno Setup installer with shortcuts and uninstall registration, so end users get a familiar install flow.
