Store description excerpt
Gwansang measures the three courts and the twelve palaces from a single photograph of a face, then places the traditional Ma-ui reading next to the numbers it actually measured. ■ Measurements, not a score "The gap between the brows is 1.17 times the length of one eye." The app shows you the number it measured, where it measured it, what the classical text asked for, and how the two met to produce the sentence you are reading. There is no overall score and no grade. ■ The measurement lines sit on your photograph Hairline, glabella, base of the nose, tip of the chin. Four horizontal rules are drawn straight onto your photograph so you can see for yourself where the app measured. ■ The same photograph always gives the same values No randomness, no server. Feed the same photograph again and the same numbers come back. ■ A photograph it cannot read gets a reason, not a number If the head is tilted, turned away, or carrying a large expression, the three courts stop describing a face and start describing an angle. Rather than force a number, the app tells you what is off and by how much: "tilt 17.6 degrees, up to 8 allowed." ■ Your photograph never leaves the device The models that find the face mesh and the hairline are inside the app and the arithmetic finishes on your phone. A reading works perfectly well in airplane mode. ■ Records and comparison Pick two saved readings and see what moved and by how much. Bone does not change in a few months, so the app also says plainly that a value which moved means the photograph changed, not the face. ■ Where the normal range came from Only one of the twelve palaces was given a number by the classical texts. The rest are drawn from freely licensed portraits on Wikimedia Commons, measured exactly the way this app measures, and the app says so on the same screen. The range is common and rare, not good and bad. ■ Advertising One banner sits at the foot of a reading you have already been given. Nothing on launch, nothing before the result, and nothing locked behind an ad. The only use of the network is fetching that banner, and neither your photograph nor a single measured value goes with the request. ■ What this app does not claim Gwansang is a traditional Korean reading in the Ma-ui lineage, widely read in the Joseon period. This app shows how that tradition looks at each part of a face, beside the measurements, and does not claim that a face reveals character or the future. Please enjoy it as entertainment and as cultural material. ■ Languages Korean, English, Japanese, Simplified Chinese, Traditional Chinese.
