Gapja: a Korean Saju reading in plain English
Named for the first pair of the sixty-pair cycle, where every cycle begins.
Gapja is a Korean Saju reading app from 60Gapja, in development for 2026. Gapja builds the chart with the same tested engine as Jeolgi and reads it in plain English, following one Korean school consistently so that the same chart always gets the same reading.
Until Gapja ships, What a Saju reading tells you describes what a Korean reader looks at and in what order.
