The Astronomy Behind Your Birth Chart Is Real — Here's the Actual Math
Orim's natal chart runs genuine astronomical calculation in your phone's browser: real planetary positions, real sidereal time, real aspect geometry — computed in about 30 milliseconds, with no server and no paid ephemeris.

Most horoscope apps interpolate. Orim calculates.
Enter your birth date, time, and place — searched by name, not typed as coordinates — and Orim computes your actual chart from real astronomical mechanics: the same category of math a professional desktop astrology program runs, done client-side, instantly, for free, at /astrology/natal-chart on orim.co.
What actually gets computed
Every planet's position comes from real orbital mechanics — its true position along the ecliptic at the exact moment and place you were born, not a table of averages. Your Ascendant, the sign rising on the eastern horizon at your birth, is derived from the actual rotation of the Earth at that instant. Every aspect — the meaningful angles between planets, like a trine or an opposition — is the real angular distance between two real positions, checked against the traditional aspect angles and their allowed orbs.
All of it runs in around 30 milliseconds, entirely inside your phone's browser. No round-trip to a server, no paid astronomy data license, no waiting.
Two ways to look at it
Your chart displays as a classic wheel, or as a linear house-by-house ladder — toggle between them freely.

Every planet, sign, house, and aspect on the chart is independently tappable. Tap a placement, and a card opens with what it means for you specifically.

The writing itself
Every placement's meaning comes from a large authored library — over 700 individually written interpretations, covering every planet in every sign, every planet in every house, every house cusp in every sign, and every major aspect pairing. There's no live AI writing your reading; a real person wrote all of it in advance, and your specific chart selects exactly which entries apply to you.
A few, as written:
Sun in Scorpio: "You don't do casual. The thing you're not saying is louder than anything you've said."
Sun conjunct Moon: "Want and need speak with one voice here. No second opinion to talk you down."
Mars in the 10th house: "You'd burn the bridge to win the building. The title you're chasing won't say your name back."

Understanding it, not just reading it
The first time you open your chart, a short guided walkthrough takes you through it chapter by chapter, so the wheel means something before you're handed verdicts.
Beyond your own chart, Orim's learn section teaches the actual mechanics behind the math for anyone curious — how software finds a planet's position, what a Julian day number is and why astronomy needs one, the real geometry behind an aspect, why your rising sign needs an exact birth time, and why two zodiac systems can disagree by 24 degrees. These aren't marketing pages; they're genuine explainers of the underlying science.

Take your chart with you
Once you're finished exploring, your chart becomes a shareable image in one tap — the wheel itself, framed and ready to post, with an option to hide your exact birth date first if you'd rather keep that private.
