Not another horoscope app

Why it feels different

☉

Your whole chart, not your sun sign

Houses, aspects and daily transits, computed from your exact birth time and place with professional-grade precision.

☿

It remembers Tuesday on Thursday

Mention something once and your coach carries it forward — and connects the sky to it when the timing matters.

☾

There at 6 a.m. and at midnight

AI-powered and always on — the depth of a private astrologer, without booking a session three weeks out. Whenever it actually hits.

More than a daily reading

Your chart is the front door. Behind it, a whole practice.

Compatibility from two real charts

Run a synastry test with your partner, your crush, or your best friend. Share a link, they add their birth data, and the full reading opens for both of you.

A tarot card, every day

Pull your card of the day and let your coach read it against your chart and what you're living — not a generic card meaning from a booklet.

Check-ins & a private journal

Log your mood in one tap and journal what's moving. Your coach remembers, and connects the sky to it when the timing matters.

Your week, every Sunday

A weekly digest reads the sky ahead against your chart — the days to push, the days to protect — so Monday never blindsides you.

Questions, answered

How is this different from Co-Star or other horoscope apps? +

Those apps generate one-liners from your sun sign and push the same notification to millions. StellarCoach works from your complete chart and remembers your actual life — what it tells you on Thursday builds on what you shared on Tuesday.

How accurate are the calculations? +

Our charts are computed with professional-grade astronomical data — the same class of engine professional astrology software relies on. Automated tests verify our charts against published professional reference charts to within 2 arcminutes.

Is my coach an AI? +

Yes — and we're upfront about it. The astrology itself isn't AI — your chart and transits are deterministic astronomy, computed from real astronomical data. The coaching conversation runs on state-of-the-art AI, which is exactly what makes a coach that remembers everything and answers at 3 a.m. possible.

What happens to my data? +

Your birth data and conversations are used only to coach you. They're never sold or shared, and you can delete your account — and everything with it — at any time.

What languages does it speak? +

English and Spanish, fully — the coach, your daily readings, the whole app.

Do I need to know my exact birth time? +

Yes — your rising sign and houses depend on it. It's on your birth certificate, and onboarding walks you through it.

How much does it cost? +

It's free to start — your full chart, daily readings, and the coach. Create your account and you're in, right away.
