Omalc

A fast, native Qt Quick calculator that integrates with Omarchy: it inherits the active theme colors and follows system light/dark mode and desktop text scaling. Basic mode with operator precedence and familiar percentage behavior; scientific mode with trigonometric, inverse, hyperbolic, logarithmic, power, root, factorial and constant functions in degrees and radians; unit conversion for currency, length, mass, temperature, area, volume, speed and data; calculation and saved-conversion history. Currency rates come from Frankfurter with local caching for offline use; everything else is offline. Mouse and keyboard operation, with shortcuts to switch modes (Ctrl+1/2/3) and open history (Ctrl+H). Install the omacalc package from the Omarchy Package Repository or build it from source with Qt 6.
