The story the heavens wrote at the moment you were born.
Read your Four Pillars, Zi Wei chart, compatibility and tarot from a single birth date — and ask the AI Master.
SajuPrime brings the essence of East Asian destiny studies into one app. Enter your birth date and time and it builds your Four Pillars (Saju), then automatically calculates your Five-Element balance, the strength of your Day Master, and your Yong Shin (favorable element) — so you can see the balance of energy you were born with at a glance. You don't need to read a traditional almanac to understand the story written the moment you were born.
It goes far beyond a single reading. A Zi Wei Dou Shu star chart maps your life across the Twelve Palaces, a compatibility view compares two charts with a score and Five-Element relationships, and a tarot draw speaks to today's question. Tarot and fortune readings aren't just generic card meanings — they are woven together with your own Saju (Day Master and Yong Shin) through an AI Deep Reading that points to the message you need right now.
Each morning you can check your daily fortune score and the auspicious/inauspicious guidance, and whenever something is on your mind you can ask the AI Master directly. SajuPrime supports English, 한국어, 日本語 and 中文, and is available now on Google Play for Android, with the iOS App Store version currently under review.
