About this app

Ohaeng helps you explore Korean Saju, the Four Pillars tradition, in clear English. Enter your birth details to see your chart and its Five Elements, then trace every character, term, and calculation step for free. Whether or not Korea is on your travel list, you can use it for self-reflection and notes on Korean culture, with optional in-depth AI interpretations available through in-app purchases.

Korean Saju shares its Four Pillars roots with Chinese BaZi, with its own Korean terms and ways of reading.

Explore your calculated Four Pillars and five elements, then open details to trace the chart characters. Add your destination, dates and companions to consider travel conditions through a traditional Saju perspective. Show Korean question cards in person, notice colors and materials in dancheong, hanbok and ceramics, and save your observations and trip reflections.

Three tabs connect the experience: Korean Saju, My trip and Records. Chart calculation and learning, field questions, culture journaling and trip records are free. Optional AI-written interpretations use existing Bok in-app purchases when you want deeper understanding or have a new travel question or condition. Review the cost and data-sharing consent before each request. Reopen a purchased result without spending again.

Available in Korean, English, Japanese, Simplified and Traditional Chinese. Unknown birth time and birthplace time zones are supported. City-level bearings do not create attraction routes or bookings. Interpretations and cultural associations are reference material, with no promise of luck, health, safety or outcomes. Private notes are device-only; server records depend on the anonymous session and do not promise cross-device restoration.
