Asteria

Astrology · Tarot · for iPhone

The sky,
shown working.

Your chart on the ephemeris 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 — computed to the arc-minute, written to be read.

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.

Three collector decks, all 78 cards each, scanned from the physical decks.

Draws from quantum randomness — debiased hardware entropy, not a pseudo-random shuffle.

Ask

Answers that cite their sources.

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.

Match

Compatibility, with the math showing.

A 0–100 score that shows its decomposition — western synastry 80, Chinese cycle 12, life paths 8.

Real synastry aspects between two charts — orbs included.

For the savage version, try the Roast below.

The ritual

Twenty-two doors,
three decks.

Tarot de Marseille, Rider–Waite–Smith, Thoth — all 78 cards of each, scanned from the physical cards. 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.

The receipts

Trust is a feature.
We engineered it.

01

Swiss-grade ephemeris

Positions computed on the same data professional astrologers use, to the arc-minute. This page's browser math admits to about a degree; the app never has to.

02

Quantum draws

Tarot cards are drawn from debiased hardware entropy — true quantum randomness, not a pseudo-random shuffle.

03

On your device

Your chart, readings and journal are computed and kept on the phone. Delete your account, and everything is wiped — for real.

04

No ads. No trackers.

We sell a subscription, not your attention. No ad networks, no data brokers, no dark patterns.

No ads. No trackers. 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 come from Swiss-grade ephemeris data, computed to the arc-minute — planets, houses, aspects, patterns, with Chinese astrology and numerology read in the same interpretation. Every claim in the app 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, readings and journal live on your phone; delete your account and everything is wiped. No ads, no trackers, no data brokers.

What makes the tarot draws actually random?

Cards are drawn from debiased hardware entropy — true quantum randomness, not a pseudo-random shuffle. 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.
