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, read alongside the traditions that have studied the sky longest. A compass through life, not a crystal ball. YOUR SKY REPORT Each New Moon, a report gathers what you wrote, the sky it met, the patterns that keep coming back, and what returns next. A Yearly report arrives at your solar return. Tell it "This landed" or "Not me" and it listens. The report and everything you wrote are free. THE TRADITIONS Western astrology from Hellenistic to modern, Vedic charts, BaZi, the Maya Tzolkin, Tibetan astrology, the Tong Shu almanac, Feng Shui flying stars, Hermetic Qabalah with your tarot birth cards, numerology, tarot and the I Ching. Choose the ones that speak to you; the app follows your choice. YOUR OWN RECORD Journal, check in, and edit any entry later. Each entry keeps the sky it was written under, so when that sky returns you can see what you wrote last time. Tag by feeling, milestone and tradition, and related entries gather into threads. YOUR CHART, PIECE BY PIECE Blueprint teaches each placement, angle and aspect, then asks you to name how it lives in you, until it is yours and not just words on a page. WHERE YOU THRIVE Your chart mapped onto the whole planet. Score thousands of cities for love, work, vitality and growth, compare them side by side, and trace the Lots too, Fortune, Spirit and six more. WHEN TO ACT Daily sky, moon phases and the transits touching your chart, from today out to the year. Electional timing reads three ways, Medieval, Hellenistic and Vedic, with the conditions each tradition names. A FULL READING, NO AI NEEDED A complete natal reading composed on your device from a deep interpretation library. Optional AI interpretations work with your own Anthropic API key, so your chart goes straight to Anthropic, never through us. SHOWS ITS WORK Every technique names its sources: the tradition, the text it rests on, and the method behind the number. Zodiacal releasing, firdaria, profections, returns, horary, progressions, solar arc, BaZi, Vedic, Feng Shui, the Maya Tzolkin, numerology, Hermetic Qabalah and tarot all cite the lineage they come from. RITUAL, DIVINATION AND SKY LETTERS Guided practices for each moon phase. Draw a tarot spread or cast the I Ching. Seal a letter to a later self under tonight's sky; it opens when the moment you choose returns. TOGETHER Synastry, composite and the places that hold you both, or group mode for three to six. Invites are encrypted end to end. REAL ASTRONOMY, NOTHING LINKED TO YOU Positions come from a built-in VSOP87 engine, not a borrowed API. Your chart is computed on your device. There is no account, nothing the app collects is linked to you, and Settings can erase everything. Celestium Premium opens the full app: unlimited saved charts, couples and group mode, the full city atlas, export and shareable cards, deeper Sky Reports, and the full depth of Blueprint, your reading and the year ahead. Subscribers can also use Premium on the web. Astrology here is for reflection, not prediction. A way to read the weather instead of a forecast you have to obey.
