Astro93: Birth Chart Astrology

YOUR CHART IS FREE AND STAYS FREE.

Astro93 is a personal astrology companion built on a simple promise: the astronomy is free, private, and works offline. Your natal chart, today's transits, and the lunar calendar are computed entirely on your device with professional-grade planetary math — no account, no ads, no trackers, no internet required.

WHAT'S FREE — FOREVER
• Full natal chart (birth chart): Sun through Pluto plus Chiron and the North Node, Ascendant and Midheaven, houses and aspects on a beautiful chart wheel
• Precise daily transits to your own chart — real astrology, not a generic zodiac horoscope
• Lunar calendar: Moon phases, New and Full Moons, sign ingresses, and void-of-course windows
• Multiple birth profiles — family, friends, partners
• Works with unknown birth time (chart without houses)
• Four house systems — Placidus, Whole Sign, Koch, Equal — plus adjustable aspect orbs
• Type a birthplace and Astro93 finds the coordinates
• A calm, dark design made for late-night sky reading

WHAT'S PRO (AI) — AND WHY IT'S PAID
PRO adds AI-written readings grounded in your actual chart:
• A daily morning briefing woven from your real transits — and it remembers previous days, so a week-long Pluto transit reads as ongoing inner work, not a daily "revelation"
• Tap any transit, placement, or aspect for a warm, psychologically grounded interpretation
• A complete natal analysis — a keepsake reading of your whole chart, exportable as PDF, also available as a one-time purchase with no subscription

Every new user gets a 3-day free trial of PRO. And the honest part: only the AI is paid, because it costs us too. Everything the app can compute itself stays free, forever.

PRIVATE BY DESIGN
Your birth data lives on your device. No account, no login, no analytics, no advertising SDKs. Only two things ever touch the network: AI readings (PRO) and birthplace lookup.

Astro93 treats astrology as a lens for self-reflection — never fortune-telling, never doom. If you know the difference between a horoscope and a birth chart, this app was made for you. If you don't yet — your chart is one tap away.
