Horoscope! is an AI-powered astrology and tarot app built for people who know nothing about either. Tell it when and where you were born; AI explains your chart, your day and every card you draw in plain words — using your own chart as the example, not a paragraph written for a twelfth of the world.
Every planet, every line on the wheel: tap ✦ and AI explains it.
Made for beginners
The first launch is a short guided tour: what a birth chart is, what your Sun, Moon and Ascendant mean, what each tab does, and why the app asks for your birth time. It ends with your first AI reading of your own chart, right there.
After that, AI is at the top of every screen, and every technical word has a ✦ next to it — houses, aspects, orbs, transits, reversed cards, spreads. Tap it and the explanation opens in place, in plain words, with your own chart as the example. You never have to leave the screen you're on.
AI explains what's on the screen; it doesn't tell fortunes. It describes the texture of a chart or a card, never predicts specific events, and never scores your day.
Features
Which points of your chart today's planets are touching, and what that feels like — written for you each day, from transits computed for your chart specifically.
AI starts with what a birth chart even is, then your Sun, Moon and Ascendant. Every position, aspect and house has a ✦: tap it to learn what it means for you.
78 cards drawn for this app, five spreads. Once the cards are turned, AI reads each one in its position, then ties them together and back to your question.
Add someone and AI explains where you pull together, where you rub, and where you complement each other — as intensity and tension, never a compatibility score.
Vocabulary
Squares and oppositions are drawn in cool violet, trines and sextiles in cyan. Not red and green: in this context red and green get read as lucky and unlucky, and that isn't what an aspect is.
Squares, oppositions. Friction, and the work that comes out of it. Not misfortune.
Trines, sextiles. Things that come without resistance — which also means without much pressure to use them.
The AI keeps the same rules as the rest of the app: no score out of 100 for your day, no compatibility percentage, no predictions of specific events. Astrology describes texture. It doesn't forecast.
How it's computed
The chart is computed on your iPhone, and the AI only writes the words: every position it refers to is checked against the computed chart before it reaches your screen. Here's what the numbers underneath come from:
| Sun, Moon | Meeus, Astronomical Algorithms, ch. 25 and ch. 47 (ELP-2000/82, truncated). Matches the book's worked examples to 0.00001° and 0.000001°. |
|---|---|
| Planets | JPL Approximate Positions of the Planets — Keplerian elements with centennial rates, light-time corrected, precessed to the date. Sign ingress dates land within 2 days of the published values; Pluto near a station is the worst case at 1.55 days. |
| Mercury retrograde | All six 2026 stations match the published tables, worst case 0.45 days. |
| Time | IANA time zone database, with historical daylight saving. China observed DST from 1986 to 1991 — get that hour wrong and the Moon is off by half a degree, which is enough to cross a sign boundary. |
| Zodiac | Tropical. 0° Aries is the vernal equinox, not a fixed star. |
| Houses | Placidus, whole sign, equal. Above the polar circle Placidus has no solution; the app falls back to equal houses and says so on screen rather than silently handing you a chart that matches no other software. |
This is good enough for astrology — a sign is 30° wide and an orb is 6°. It is not observatory-grade: don't use it to time an occultation.
Privacy
No analytics SDK, no advertising. Your birth data, readings and notes are stored on your iPhone. When AI explains something, only the computed positions (or the cards drawn and your question) are sent to write the text — never your name, birth date or birthplace. You sign in with Apple; we keep only an irreversible ID.
Birth date, time and place — the guided tour tells you why each one matters. Don't know your birth time? Say so; the app still works, and tells you which parts of the chart to take lightly.
