Heartloop

Saju · Tarot · Zodiac · MBTI — one place, four ways to ask "what's actually going on with me?"

Most fortune apps give you a single-paragraph horoscope that could apply to anyone. Heartloop starts from your actual birth data — year, month, day, and (if you have it) hour — and runs it through a traditional Korean Saju (Four Pillars of Destiny) calculation engine, then layers AI-assisted interpretation on top so the reading responds to your specific chart, not a generic template.

You can also draw a real Tarot spread, check your Western zodiac forecast, or explore how your MBTI type actually behaves in love and work — and cross-reference all four against each other.

What people actually ask before trying this

How is Saju different from Western astrology?

Western astrology reads one zodiac sign from your birth day. Saju builds a chart from four separate pillars — year, month, day, and hour — each with its own Heavenly Stem and Earthly Branch, for eight characters total ("Saju Palja"). It's a far more individualized system than a single sun sign.

Do I need my exact birth time?

Only the hour pillar needs it, and it changes roughly every two hours. Year/month/day pillars work from your date of birth alone. If you don't know your birth time, Heartloop still generates a reading from the other three pillars and flags which parts are time-sensitive.

Is it free?

Each category has a free basic reading. Deeper reports (career timing, wealth flow, detailed compatibility, etc.) unlock individually per report — there's no single bundle that unlocks everything at once.
