What is this

Astrology is old. Honest arithmetic about the sky is older. We just put the two back together.

Computed, not vibes

Charts are calculated on Swiss Ephemeris, the professional standard, and printed to the arc-minute. The math is checkable in any serious tool.

Receipts on every claim

Each interpreted line opens a why-panel: the exact dignity, sect, orb, and house system behind it. Disagree with the reading? Audit the engine.

Honest about the limits

Interpretation is a lens, not a forecast. The astronomy is exact; the meaning is yours to take or leave. No fear, no flattery, no fortune-telling.

Understand your birth chart

Unlike magazine horoscopes that use only your sun sign, diosa computes the complete sky at your birth moment: every planet, the rising sign, and the houses. Then it shows you the math.

Questions

Asked often, answered honestly.

What makes diosa different from other astrology apps?

Every reading shows its work. Positions come from Swiss Ephemeris, the same calculation library professionals use. Each interpreted factor carries a receipts panel: dignity, sect, aspect orb, house system. If the engine can't prove a chart fact, the app won't claim it.

Is diosa free?

Casting your birth chart, the sky screen, and transits are free. Create a free account and your chart is saved and synced.

What is a birth chart?

A snapshot of the sky at the exact moment and place you were born: every planet's zodiac position, the rising sign, and the house layout. Our guide, the birth chart explained, walks you through yours.

Which house system does diosa use?

Whole-sign houses by default. It's the oldest and least ambiguous system. Placidus is there too if you want to compare. Every receipt panel prints the house system in use, so you always know which lens you're reading.

Why does my birth time matter so much?

The Ascendant moves about one degree every four minutes, and it sets your whole house layout. A rounded or guessed time can shift your rising sign and every planet's house. diosa asks you to confirm your timezone and flags uncertain times instead of hiding them.

Is astrology scientific?

Honestly? Its interpretations are not testable science, and we won't pretend otherwise. What diosa does promise is different: the astronomy is exact, the method is documented, and every claim is auditable. You're invited to check the math. That's the product.

What happens to my birth data?

We treat it as sensitive. It lives in your own row, protected by row-level security, and it's never sold or used to train models. Delete your account and it goes with you.

The sky hasn't changed.
The way you read it should.
