Your pet has a
birth chart
Aetris maps your dog or cat's Sun, Moon and Rising, and when the birthday is unknown, estimates them from behavior. Start with their birth date.
No birthday? Ten behavior questions in the app estimate the whole chart.

Sun, Moon, and Rising — the sacred trinity
Who they are, what they feel, and how they meet the world. Read from ten questions about how they behave, so no birthday is needed, and written for your pet alone — never a widget that rotates fortune-cookie text.


No birthday?
No problem
Most rescue pets arrive without a birthday. Aetris asks ten questions about how your pet behaves and works out their Sun, Moon and Rising from the answers. It's a reading of how they live, not a recovered birthday.
Answer
Ten questions in three short acts: four for the Sun, three for the Moon, three for the Rising.
Light
Each answer points to an element or a mode, and together they light each sign. AI writes the words, not the signs.
Read
Sun, Moon and Rising, with a profile written for your pet and a star passport to keep.
Refine
Tell the app how their days really go. The nightly ritual and the Bond score learn from it.
The chemistry between you, rendered
One number for today, built from three things: your sign read against theirs, where the Moon sits tonight, and what you logged about the day they actually had. It moves every morning — and until you have logged anything, it says so rather than inventing a bond it never measured.


One card, drawn from their chart
Every sunrise, a new card — channeling Mars, Moon, or Venus. Added to your Grimoire forever. Collect Cosmic Dust through daily rituals. Legendary cards arrive only with the sky: a full moon, an eclipse, Mercury turning retrograde.



One of twelve signs. One of forty-eight beasts.
Twelve families, four beasts in each — and the moon phase on the day they were born names which of the four is theirs. Every Scorpio is a Scorpion, a Panther, a Snake or a Raven; the sky already chose. Birth date alone is enough, no birth time. Yours is named too, and the two are read as a pair.
