Hunter eyes are not a vibe, they are three measurements: a positive canthal tilt, a narrow vertical eye opening, and a brow that sits close to the eye. Symmi measures all three and tells you which you have.

How it is measured
The tool levels the head, then measures each eye. Tilt is the corner-to-corner angle. Aperture is the vertical opening divided by the horizontal width, so it does not depend on photo scale. Brow distance is the gap from the eyebrow's lower edge to the upper eyelid, divided by eye width. Orbital depth, the fourth thing people mean by hunter eyes, cannot be measured from a flat photo; the app's 3D scan measures it.

FAQ
A set of features, not a single thing: upward-tilted outer corners, a narrow, almond-shaped opening, a brow that sits low over the eye, and deep-set sockets. Most people have one or two of the four. This tool measures three.
Tilt and orbit are bone. Aperture and brow position have a soft-tissue component: the orbicularis and the brow depressors respond to training, and a lower brow narrows the apparent opening. The Symmi app builds that routine and tracks the readings between scans.
Forums rate from a photo by eye. This measures. The two disagree most on canthal tilt, where landmark measurement reads a few degrees lower than what people quote.
