BornUnder is built on one discipline held all the way down: the computation is fact, and the meaning is a named tradition's reading — and the two are never blended. Every position, time, and orb in every reading is computed from the actual heavens using the JPL ephemeris, the same planetary data used for spacecraft navigation. Every interpretive sentence is attributed to its source — the Hellenistic tradition of Valens and his era, or, clearly fenced as a modern hypothesis, John Addey's harmonics — and offered, never asserted.
We call it astrology with receipts: beneath the prose of a reading run the ⌗ lines — the computed facts each claim rests on, dated and quoted, so you can check the working. No other astrology app can print that line under its sentences.
A BornUnder reading is a document, not a feed. It is written once, at depth, and kept — it reads the same tomorrow as today. There are no streaks, no nudges, no notifications engineered to pull you back. Come when the sky is worth it.
The real sky over your city — positions, aspects, the Moon's void hours, and a full daily reading through the tradition — is free. The deep personal documents — the Gold Natal portrait, the Year's Governor, the world-first Addey Chart — are priced plainly when they're offered, with nothing hidden and no subscription required to see the heavens.
Every reading is bound to standing commitments: orientation, never prediction — the sky's weather is described, outcomes stay yours. Recognition is offered, never declared. Nothing is invented where the facts fall silent. The length of a life is never computed — a permanent refusal. And the readings are composed under practitioner-vetted doctrine, with any finding corrected once at the source and inherited by every reading after it.
The meanings in these readings are inherited, not invented — worked out roughly two thousand years ago in the Greek-speaking world around Alexandria, where Babylonian star-lore, Egyptian temple craft, and Greek geometry poured together into a single discipline. We follow that oldest complete layer because it is the root system everything later grew from — stricter, stranger, and more honest than the flattened echo that survived into newspaper columns. Where the tradition speaks with many voices, we say so and name the line we follow. Where a technique matured centuries later, the reading says "the later craft," in as many words. Where the sources fall silent, the reading does not raise its voice to cover the gap.
Every doctrine these readings lean on was verified against the sources — the ancient authors in modern scholarly translation: Dorotheus of Sidon (Carmen Astrologicum, tr. Pingree), Ptolemy (Tetrabiblos, tr. Robbins), Vettius Valens (Anthology, tr. Riley) — the single deepest well here — Porphyry (Introduction, tr. Holden), Paulus Alexandrinus (Introduction, tr. Greenbaum), whose worked example of the year-governor this app's engine matches ordinal for ordinal, Firmicus Maternus (Mathesis, tr. Holden), and Abū Maʿshar (On the Revolutions of the Years of Nativities, tr. Dykes); checked page by page against the modern scholarship of Demetra George (Ancient Astrology in Theory and Practice) and Chris Brennan (Hellenistic Astrology). Most of these techniques vanished from the West for centuries and were recovered only in recent decades, through translations like these. What you are reading is not a continuation of the newspaper line — it is a return to the source, carried out with the sources open on the table.
And one more honest word: we keep a standing record of every editorial decision behind these readings — every attribution checked, every wording corrected, every place the documentation was found overselling and cut back. That record includes an adversarial review — the concordance of sources was deliberately attacked, objection by objection, and amended wherever an objection landed. The sky is computed. The meanings are inherited. The difference is always labelled. That is the whole method.

BornUnder is made in Brisbane, Australia, by a keeper who wanted astrology that could survive an honest question — and read letters from its visitors personally.
