The astrology app
that shows its work.

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.

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

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.

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.

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.

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.

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.
