TruHu

TruHu is a macOS‑based utility that calibrates a monitor’s color output by leveraging a smartphone as a reference device. The application guides the user through a series of steps, capturing color measurements with the phone’s camera and adjusting the display settings to achieve a more accurate and consistent visual appearance. It is intended for anyone who needs reliable color reproduction on their screen, such as photographers, graphic designers, video editors, and other visual professionals who work on macOS systems. What sets TruHu apart is its reliance on a readily available mobile phone for measurement, eliminating the need for dedicated hardware colorimeters while still providing a stable, production‑ready calibration workflow.
