Starlight Astrology

Starlight Astrology is a complete astrological analysis toolkit that combines Western astrology with BaZi (Chinese Four Pillars), numerology, astrocartography, and synastry — all in a single app, with no account required and no data ever leaving your device unless you choose to look up a city.
WESTERN NATAL CHARTS

Generate a full natal chart wheel using the Placidus house system, with all ten planets, the lunar nodes, Lilith, Chiron, and the four angles (Ascendant, Midheaven, Descendant, Imum Coeli). Every placement comes with essential dignity scoring, retrograde detection, and a dispositor chain so you can see exactly how the planets in your chart relate to one another.
LIVE TRANSITS

See what's happening in the sky right now — or on any date you choose — and how it's currently activating your natal chart. Transit-to-natal aspects are calculated in real time, with full interpretive readings for every active transit.
HOUSES & ASPECTS

Detailed house-by-house breakdowns with rulers, occupants, and sign-on-cusp interpretations. A full aspect grid covers both major and minor aspects, each with orb display and nature classification.
ARABIC PARTS (LOTS)

Calculate the Lot of Fortune, Lot of Spirit, Lot of Eros, Lot of Victory, and more — each with day/night chart-aware formulas and house placement interpretations.
BAZI — FOUR PILLARS OF DESTINY

A full Chinese BaZi reading alongside your Western chart: Year, Month, Day, and Hour pillars with Heavenly Stems, Earthly Branches, hidden stems, Day Master strength analysis, and Ten Gods relationships.
NUMEROLOGY & TAROT CORRESPONDENCES

Life Path, Expression, and Soul Urge numbers, with master numbers preserved. Tarot correspondences map your planetary placements to their archetypal cards.
ASTROCARTOGRAPHY

Forty planetary lines mapped across the globe, with domain-based key lines for wealth, health, love, career, growth, challenge, creativity, and spirituality — see where in the world different parts of your chart are most activated.
SYNASTRY

Compare any two saved charts for full cross-aspect relationship analysis.
PRIVATE BY DESIGN

All of your chart data stays on your device. There's no account, no server-side database, and no tracking. The only outbound network request the app makes is an anonymous city-name lookup when you add a birth location — nothing else about you or your chart is ever transmitted.
WHO IT'S FOR

Whether you're new to astrology or have been practicing for years, Starlight Astrology gives you professional-depth calculations validated against reference ephemeris data, wrapped in a clean, fast interface designed for genuine daily use — not just a novelty horoscope app.
A small one-time unlock ($5.00) supports continued development and gives you full interpretive readings across every tab. Core chart calculation and viewing is always free.
