Constella: Daily Reading
Korean astrology saju, one card a day
Constella reads your saju: five elements, useful god, and chart structure. Each day drops a single card on your day pillar, with twelve life domains a tap away: career, love, health, study, travel, balance. Offline by default. No ads, no subscription. Only deeper readings cost one ticket.
I built Constella because every saju app I tried was either three pop-up ads deep, locked behind a subscription, or just printed a
generic daily horoscope. I wanted the actual reading (five elements, useful god, chart structure) without selling my birth data to
do it.
So Constella does three things:
🌙 A real saju engine. Five elements in balance, strength reading, useful god, and chart structure. The bones of the eight
characters you were born with, not surface zodiac.
📅 One card a day. Sitting on the day pillar of the moment, stacking on a calendar so a month's drift shows at a glance. Twelve life
domains unfold from a tap.
🔒 Offline by default, no ads. Saju is computed on-device. Your birth data never leaves your phone. Deeper readings cost one star
ticket. Tickets never expire, no subscription.
Also in there: Compatibility for laying two charts side by side, Bond Search (opt-in, nearby charts that echo yours), Life arc
covering early, middle, and later years, and a New Year reading that opens one step earlier with a ticket.
Five languages: Korean, English, 简体中文, 繁體中文, 日本語.
Would love feedback, especially from anyone who's read saju before. What rings true, what should I dig deeper on?
