ARO runs your day through four independent analyses.
■ Four engines must agree
Saju (Four Pillars) + Western astrology + biorhythm + numerology.
One voice alone is just a guess. When all four point the same way, it counts. No guessing mode consensus only.
■ Lifetime chart + today's 30-cell matrix
Enter your birth info once and get a full lifetime reading. Every day, the four engines recalculate a 30-cell matrix across money, love, work, health, growth, and family — see at a glance where things open up and where they jam.
■ You and them — why is it like this?
Compatibility that reads psychology alongside Saju, from the bright side to the shadow side. "Why don't we click?" finally gets an answer.
■ How's my dog or cat today?
A dedicated five-engine reading for pets. No birthday? Adoption day works too.
■ Serious about accuracy
DST hour correction (1948–1960, 1987–1988), true solar time adjustment, and a verified calendar library — accurate even for first-generation charts.
■ Free + ads + ARO Pro
