Celestium: Cosmic Compass

Go deeper than your sun sign. Read your whole birth chart, find where on Earth you thrive, and time your next move with the sky. Private, on your device, no account.

Celestium isn't a horoscope written for millions at once. It's your actual birth chart, the real sky of the moment you were born, made into something you can explore and understand for yourself. A compass, not a crystal ball.

YOUR CHART, PIECE BY PIECE Meet your chart one piece at a time. Blueprint teaches each placement, angle, and aspect, then asks you to recognize it and name how it lives in you, until it is yours and not just words on a page. Watch the ring fill as your whole chart comes into focus.

WHERE YOU THRIVE Your birth chart, mapped onto the whole planet. See the lines that follow you and the places that light up, and score thousands of cities for love, work, vitality, and growth. Compare places side by side. Planning a move, a trip, or a fresh start? Find the ground that backs you. A second layer traces the Arabic Parts too; Fortune, Spirit, and six more. See where a single theme like luck or vocation gets loud, apart from the city score.

WHEN TO ACT Daily cosmic weather, moon phases, and the transits actually touching your chart. Open to a short daily almanac that centers you in the sky of the day, then zoom from today out to the year and catch the windows worth using and the ones worth resting through. Log a quick check-in against the moment, tag it to a saved chart or your own cycle phase, and let what repeats show itself.

A FULL READING, NO AI NEEDED A complete, written natal reading, composed on your device from a deep interpretation library; no account, no API key. Want more? Optional AI interpretations work with your own Anthropic API key, so they stay free and your chart goes straight to Anthropic, never through us.

RITUAL AND DIVINATION Guided practices for each moon phase; small ways to mark a threshold instead of letting it pass. When a question sits with you, draw a tarot spread or cast the I Ching.

SKY LETTERS Write a letter to a later self and seal it under tonight's sky. It stays closed until the moment you choose returns; the next new moon, the next full moon, or a year from now; then it finds its way back to you.

TOGETHER A second chart for couples: synastry, composite, and the places that hold you both. Or go wider with group mode for three to six. Invites are encrypted end to end, so only you can read what passes between you.

REAL ASTRONOMY, YOUR DATA STAYS YOURS Positions come from a built-in VSOP87 engine, accurate to about a degree, not a borrowed API. Even a slow mover like the North Node updates the day it actually crosses, not weeks after. Your chart is computed on your device. No account. No tracking. It never leaves your hands unless you choose to send it.

Optional add-on: a personal audio natal reading, voiced to fit your chart. It is a paid service, separate from the app.

Celestium Premium unlocks the full app: unlimited saved charts, couples and group mode, the full city atlas with advanced filters, export and shareable cards, and the full depth of Blueprint, your reading, and the year ahead.

Astrology here is for reflection, not prediction. A way to read the weather instead of a forecast you have to obey.
