ConstCalc is a construction-focused calculator for Android that makes imperial feet-inch math (with inch fractions) fast, readable, and consistent across tasks. It bundles four calculator modes—Basic (imperial), Mixed (trade shortcuts), Advanced/Scientific, and Unit Convert—behind a simple top-bar UI. A Settings page lets you control light/dark themes (or follow device), “bevel/softness” of UI elements, and defaults. The app label shows ConstCalc by BBMT; current in-app version shown on Settings is V 1.0.0.
