AstroSync is a free AI-powered astrology app that generates personalised daily luck scores, compatibility analysis, and planetary transit readings based on your natal birth chart. It uses the Swiss Ephemeris for precise astronomical calculations and Google Gemini AI for personalised interpretations.
AstroSync retrieves real-time positions of the seven classical planets (Sun, Moon, Mercury, Venus, Mars, Jupiter, Saturn) using the Swiss Ephemeris, then measures their angular relationships to your natal chart. Trines and sextiles add to your score; squares and oppositions subtract. Jupiter amplifies positive aspects; Saturn amplifies challenging ones. The resulting Career, Love, and Vitality scores are then interpreted into a personalised daily forecast by Gemini AI.
A natal chart (also called a birth chart) is a snapshot of the sky at the exact moment and location of your birth. AstroSync calculates it using the Swiss Ephemeris — the same astronomical database used in professional astrological software — accurate to arc-second level. All you need is your birth date, time, and city.
Synastry (called Harmony Analysis in AstroSync) compares two natal charts to assess compatibility. AstroSync computes the angular aspects between every planet pair across both charts and uses Gemini AI to generate a compatibility percentage plus breakdowns for Romance, Communication, and Long-term Stability. Add anyone by their full birth data or simply by zodiac sign.
Yes — AstroSync is free to download and use. Daily luck scores, today's reading, and harmony analysis are included at no cost. An optional Premium subscription unlocks full AI-written domain forecasts, the complete transit calendar, and up to 5 harmony connections.
Planetary positions are calculated with the Swiss Ephemeris (swisseph), accurate to arc-second level — the same precision used by professional astrologers. AI interpretations by Gemini are designed for personal reflection and self-discovery. Like all astrology, readings are meant to inspire insight, not predict specific events.
