You've been selected to test the Asteria beta.
"Asteria" is the working title you'll see throughout; the name may change before launch, the tools won't. I've been building these so anyone, beginner to advanced, can get to know the stars and have them speaking to you right in your pocket.
a note on what you're reading: the chart math (positions, houses, aspects and historical timezones) is computed precisely. the written interpretations are mine, and still being tuned. this is an early build, so if something looks wrong or rough, that is exactly what I want to hear.
send me anything: a voice memo, an email, or a quick text about what worked and what didn't. I'm aiming for a public launch later this year, with profiles, cloud-saved charts, and a final name. want to know when it's live? reply to your feedback and I'll add you to the launch list.
one ask: this is a private, invite-only beta. keep the link and any screenshots confidential until launch; showing a friend in person is fine.
The whole sky,
in plain language.
planets, houses, aspects, and cycles: real ephemeris math, plain sentences. transits, returns, progressions, synastry, places.
Cast your chart ↓Cast a chart.
Enter the hour and place of a birth. Type the city and the coordinates are looked up for you, and the timezone resolves to the right historical offset, daylight saving included. The closer the birth time, the sharper the chart.
beta: birth details stay on this device. nothing is uploaded.
clearing site data or switching browsers removes local charts. keep a copy of birth details if you need them.
Where should you start?
No account needed. Your answers stay in this browser and shape a short reading list: three links, in order.
Do you know your Big Three?
Sun, Moon, and Rising: the three anchors most charts open with.
Do aspects feel confusing on a chart wheel?
The colored lines connecting planets, conjunction, square, trine, and the rest.
What do you want from Asteria first?
You can change course anytime: this just orders your first three stops.
