Observe, mark, interpret

A setup check, not another calibration ritual.

Hardware calibration can be correct while today’s position is not. Gaze Calibration Card checks the pointer you already use, then gives you a plain-language signal before a frustrating session.

Private by construction

Camera frames never enter the app.

The app observes only the pointer position your existing gaze software exposes to the operating system. There is no login, cloud sync, advertising, or analytics. Notes and checks stay in local app storage until you remove them.
