Sample card for Maya and Jo, best friends: One of you starts things. The other one was already starting things.

Astrology in plain English.

Your day, according to your actual chart.

Enter your birthday and get a short reading that explains itself. Then add a friend, a crush, or your mom and get a card for the two of you. Free. No sign-up.

Birthday Birth time I don't know my birth time

That's fine. You'll skip the rising sign and still get a real reading. The city is optional now; it helps settle your Moon sign.

Your birth details stay on this device. We never see them.

For fun and reflection. You don't need astrology, and it shouldn't make your decisions for you.

The two of you

How it works

Your birth chart is where the Sun, Moon and planets were when you were born. A transit is a planet in today's sky lining up with one of those birth positions. Overlap finds the closest line-up today and writes a short reading about it. Every reading shows its "why," so you can check it.

The pair card compares two birth charts. The same two people always get the same card.

No birth time? You still get a reading, without a rising sign.

Astrology is for fun and reflection. It isn't science, it isn't advice, and it shouldn't decide anything about your health, your money or your relationships.

Privacy

There are no accounts. Birth dates, times, places and names are saved in this browser on this device and are never sent to us. All the chart math runs on your device.

To learn whether the app is useful, we count ordinary visit statistics (pages opened, the site you came from, country and device type) and seven anonymous events: reading made, pair card made, share tapped, report button clicked, "yes" to the report question, arrived from a shared card, and return visit. None of it contains names, birth details or IDs, and we use no cookies.

Shared cards are images. They show the names you typed and the reading, nothing else.

"Delete my data" in the menu erases everything saved here.

A full report for the two of you (every connection between your charts, in plain English) doesn't exist yet. We're checking whether anyone wants it before building it. Nothing will be charged.
