Asteria

Astrology · Tarot · for iPhone

The sky,
shown working.

Your chart computed on your iPhone and checked against Swiss Ephemeris, the reference professional astrologers use. Transits you can verify against the actual sky. A tarot ritual you perform — not a button you tap. This page is already proving it: every value on it is computed in your browser, live.

The sky right now

computed in your browser ·

Your turn

The instrument — free, in your browser

Type a birthday.
Watch the work.

Any birthday — yours, a crush's, your mother's. The page computes the natal Sun and Moon, then checks today's real sky against that chart: every aspect, with its orb.

Nothing leaves this page. No account, no email, no upload — the same on-device principle the app is built on.

Zero network requests when you press the button — check the network tab.

The sky ahead — computed here

The next turns of the sky.

Lunations, sign changes, retrograde stations — the next 75 days, computed in your browser the moment you opened this page. Not copied from a blog.

The app goes further: it tells you what each of these does to your chart, the morning it happens.

One companion · five instruments

Everything reads from the same sky.

Today

One briefing, from your actual sky.

Every transit over your natal chart, read together each morning — not a caption recycled for one twelfth of humanity.

Receipts attached: planet, degree, orb — every line shows its why.

Written as a serial you follow, day after day — it remembers yesterday.

Theme

A natal chart that goes all the way down.

Planets, houses, aspects, patterns — every placement to the degree and minute, your Ascendant within 8 arc-seconds of Swiss Ephemeris.

Chinese astrology and numerology woven into the same reading — never bolted on.

Depth that compounds: the chart opens further the longer you stay.

Tarot

A ritual performed, not dispensed.

Shuffle, cut, draw — by hand. The cards tilt and catch the light like real cardboard.

Two historical decks in the public domain — the Waite-Smith of 1909 and the Marseille of Jean-Pierre Payen (1713), all 78 cards each, free.

The order comes from a quantum source when it answers, from your iPhone when it doesn't — the receipt says which.

Ask

Answers that show their sky.

Ask anything. The answer quotes your placements and today's transits — you can check its work.

It reads your whole chart, not just your Sun sign.

No flattery engine — when the sky is complicated, it says so. Phrased by AI, only if you agree.

Compatibility

Compatibility, with a score that explains itself.

A score out of 100 with each person you add, in love, friendship, family or work. A first name and a birth date are enough; their sign alone already has its reading.

What the score is made of: emotions, desire, talking, day to day, what lasts. Each part names the contacts between your two charts and says whether each one brings you closer or creates friction.

You in love: how you love and the partner who suits you. And your relationship, read as a third chart, with Premium.

The ritual

Twenty-two doors,
two decks.

The Waite-Smith of 1909 and the Marseille of Jean-Pierre Payen, printed from his woodblocks of 1713 — two public-domain decks, all 78 cards of each, free. In the app you shuffle with your finger, cut where it feels right, and the cards catch the light before they turn. Here, one gesture survives the web: draw.

Tap the deck · draw your card

The receipts

Trust is a feature.
We engineered it.

01

Checked against Swiss Ephemeris

Positions computed on your iPhone and measured against the reference astrologers use: your Ascendant within 8 arc-seconds, over 20,000 test births. This page's browser math admits to about a degree; the app goes much further.

02

A receipt for every draw

The order of the cards comes from the Australian National University's quantum source when it answers, and from your iPhone when it doesn't. The receipt under the cards says which.

03

Computed on your phone

Your chart is computed on the iPhone; your journal never leaves it. Your readings are kept in your account, on a server in the EU, so they survive a reinstall. Delete your account, and everything is wiped — for real.

04

No ads. No tracking.

We sell a subscription, not your attention. No ad networks, no data brokers, no dark patterns. Usage statistics are anonymous, hosted in the EU, and can be switched off.

No ads. No tracking. No $19.99-a-minute reassurance. We sell a subscription — not your attention, not your data, not your fear.

— the entire business model

For the group chat

Two birthdays.
One honest roast.

Real synastry — positions, aspects, orbs — computed in your browser and read slightly too accurately. Watermarked, shareable, free.

Plain answers

Fair questions.

Is this serious astrology, or a gimmick?

Serious. Positions are computed on your iPhone and checked against Swiss Ephemeris — your Ascendant within 8 arc-seconds — with planets, houses, aspects and patterns, and Chinese astrology and numerology read in the same interpretation. Every reading carries its numbers, so you can check any of it.

What happens to my data?

On this page: nothing leaves your browser — the math runs on your device. In the app: your chart is computed on your phone, your readings are kept in your account on a server in the EU, and written readings go to an AI service only if you agree. Delete your account and everything is wiped. No ads, no data brokers. The full privacy policy.

What makes the tarot draws actually random?

The order of the cards comes from a quantum random source (the Australian National University's) when it answers, and from your iPhone when it doesn't — the receipt under every draw says which. And the ritual stays yours: you shuffle, you cut, you turn the cards.

How much does it cost?

A subscription with a real free tier — priced like an app you keep, not $19.99 a minute of reassurance. No dark patterns, cancel in two taps.
