The same birth moment,
seen through four windows
They don't repeat each other; when one falls silent, another speaks. All of them read from the same computed chart.
Daily Transits
Today's sky collides with your natal chart. Not a generic sun-sign horoscope — the aspects are yours.
Birth Chart
Planets, houses, aspects. Your ascendant is only as precise as your birth time — if it's unknown, Rytho says so instead of inventing it.
BaZi & I Ching
Four Pillars analysis, Day Master strength, luck cycles; one hexagram cast a day with its moving lines.
Physiognomy
The face reading tradition. Measurement happens on your phone — your photo never reaches a server.
Your cosmic blueprint,
in three minutes
You give your birth date, time and city. The rest is computation.
Your chart is drawn
Planetary positions at your birth are computed with the Swiss Ephemeris; houses and aspects are built. You're met with a scene where the Sun, Moon and Ascendant open one by one.
It meets today's sky
Every morning the current sky is laid over your chart; the reading isn't "Aries are lucky today" — it comes out of your own aspects.
Four traditions speak
The same moment becomes four pillars in BaZi, a hexagram in the I Ching, facial proportions in physiognomy. Rytho brings them together in a single voice.
Rytho gets to know you
Only distilled insights are kept from your conversations — never raw transcripts. Over time the readings speak a language that knows you.
When the sky moves,
you'll know
Retrograde stations, full moons, streak reminders and your daily reading — all in your own time zone, with respect for your quiet hours.
We don't make it up.
We compute it.
Most astrology apps hand a few hundred canned paragraphs out to twelve signs. Rytho builds every reading from the real sky of the moment:
Swiss Ephemeris + NASA JPL
Planetary positions come from ephemeris data at millisecond precision — not a lookup approximation.
True Solar Time
BaZi pillars are corrected for longitude and the equation of time. Month pillars are built from true Jie Qi solar terms, not from the calendar.
Honest randomness
The I Ching cast uses hardware entropy and reproduces the classical yarrow distribution — 1/16 · 5/16 · 7/16 · 3/16 — exactly. All 384 line texts are in place.
Readings grounded in sources
Interpretations draw on a knowledge base of public-domain classics and Rytho's own doctrine texts — not on whatever the model happens to remember.
A guide that isn't
trying to please you
🜂 No flattery
It calls a hard period hard. We deliberately refuse to tell everyone "you have a special energy" — that sentence knows no one.
🜁 Nothing unmeasured is shown as measured
If your birth time is missing, the hour pillar is never built and you are told so. No dated prophecies, no health or financial advice.
🜃 Your face stays on your phone
Physiognomy measurement runs on your device; your photo is never uploaded and never stored.
🜄 A social layer without noise
No feed, no comment wars. A daily dyad reading with a friend and a reaction from a small closed set — with no free text, there is no harassment either.

Good questions
I don't know my birth time — is it still useful?
Yes. The ascendant and houses need a time; Rytho states clearly that the time is unknown and makes no claims there. In BaZi the hour pillar is never built — it reads with three pillars.
What's in the free tier?
Daily, weekly and monthly sign readings; the live sky screen; 5 chat messages a day; one I Ching cast a day; the friends list and streak tracking. Forever, with no ads.
What happens to my data?
Your birth data is used only to produce your readings and is never shared for advertising. Face reading is measured on your device; the photo is never uploaded. You can delete your account instantly in the app. Details in the privacy policy.
Is this a fortune-telling app?
Rytho is an entertainment and insight app. It meets ancient traditions with real astronomical computation; it gives no medical, legal or financial advice and claims no certain futures.
When is it coming to iPhone?
The iOS version is in preparation. Android is on Google Play today; when you move to iOS with the same account, your chart and subscription come with you.
