Astral EdgeEntertainment · Reflection · Not prediction
Know your sky
before it moves.
Astral Edge reads classical astrological timing against your birth chart and shows you, hour by hour, when the traditional markers stack supportively or challengingly. A reflective tool grounded in tradition — not a validated predictor. We tested it rigorously and publish what didn't hold up.
Free to start. $2.99/month for premium timing.
How it works
We pre-registered 53 astrological hypotheses.
Tested rigorously. None replicated.
So we say so.
Most astrology apps weight techniques by tradition or gut feel. We built a cohort of ~1,000 documented life events, pre-registered 53 astrological hypotheses, ran 10,000-permutation label-shuffle tests with a proper subject-level discovery / held-out split, and corrected for multiple comparisons.
Zero hypotheses replicated at BH-FDR q=0.05 across both arms. The production scorer is therefore a traditional-astrology-informed timing heuristic — a structured read of classical techniques — not an empirically validated predictor. Use it as a reflective tool, not as a forecast. Full null-result writeup is linked on the methodology page.
Cross-validated classification AUC on held-out data is 0.505 — chance. We ship the scorer as a classical-astrology heuristic, with the honest label on the tin.
Who we studied
Verified birth times, at the moments lives turned — in both directions.
Peak events: Nobel laureates, Oscar winners, Olympic golds, Grand Slam finals, Billboard #1 singles, championship athletes, documented lottery jackpots. Setback controls: convictions, resignations, bankruptcies, career-ending scandals. Rodden ratings range from AA (birth-certificate) down to noon-proxy where no birth time is publicly available. Peaks skew more timed than setbacks — a real asymmetry we don't hide.
We pre-registered 53 hypotheses and ran the rigorous test the data deserves. The result is a null: no hypothesis replicated across a clean discovery / held-out split at FDR-corrected significance. The scorer ships as a classical-astrology heuristic with that honest label — not as a validated predictor.
What we falsified
Popular astrology memes that didn't hold up in our cohort.
Three classical claims people repeat confidently on social media showed no statistically significant effect on peak events in our data. If the app ever pushes them at you, call us out.
- Mercury retrogradeSignature stressor periodNo peak/setback effect (p=0.45)
- Via CombustaInauspicious arc of the zodiacBorderline null (p=0.10)
- CazimiStrongest amplifier in traditionBorderline negative (p=0.07)
Four other classical claims — fixed-star luck conjunctions, waxing-moon favorability, Chaldean decan rulerships, a popular midpoint doctrine — also showed no significant effect. Full null list lives in our methodology notes, updated each time we expand the cohort.
Honest answers
Questions you're probably asking
Does this actually work?
No, and we don't claim it does. We pre-registered 53 astrological hypotheses and ran rigorous permutation tests with a proper discovery/held-out split. Zero hypotheses replicated at FDR-corrected significance across both arms. Classification AUC on held-out data is 0.505 — chance. The scorer is a classical-astrology-informed timing heuristic — a structured way to explore traditional techniques on your own chart — not a validated predictor. Use it as a reflective tool, not a forecast. The full null-result writeup is on the methodology page.
So why ship it at all?
Because classical astrology has been scored by hand for two thousand years, long before anyone had the data to validate it. Nearly every astrology app you've ever used is scoring things the same way — just without telling you it's theory-anchored rather than empirically validated. We're telling you.
How do I know you're not just hiding the bad results?
The opposite — we published them. Earlier versions of this page claimed 'eight survivors' and a '51% held-out lift.' When an independent reviewer audited the pipeline, those numbers turned out to be artifacts of a broken null construction and a leaky discovery/held-out split. We rebuilt the analysis correctly and the claims evaporated. All of that is documented in the research repo's research/phase1-rebuild branch. Transparency cuts both ways.
