Astrology with receipts.

Every line of your reading cites the classical source it came from, says how sure the chart is, and turns into something you can actually do this week. Then Orrery tests it against your own life.

iPhone beta this fall. Your birth chart is free, forever. One email when it's ready; no spam.

What a reading looks like

Plain words first. The source right underneath.

A good stretch for getting credit for what you do.

So what: tell the right person about your best recent result.

The source: Jupiter trine your Midheaven. William Lilly, Christian Astrology (1647), Book III, "Of the Transit of the Planets".

Positions: JPL DE440 True for 96% of your possible birth times 2 sources, 2 traditions agree Your data: 9 of 12 days like this went better than usual

Illustrative example. Your reading is computed from your exact birth minute and place, so no two are alike.

Why it's different

Built for people who want to know why.

Real astronomy

Planet positions from NASA JPL's DE440 ephemeris, accurate to under an arcsecond, computed on your phone.

Every claim cited

Over a thousand rules from four traditions (Hellenistic, Medieval, Modern, Vedic), each linked to its source. No invented horoscopes.

Honest confidence

Don't know your exact birth time? Orrery shows which parts of your chart hold anyway and which don't.

A planner, not a horoscope

"When should I ask for a raise?" Pick an intention and see the windows your sources favor, next to your own best days.

Your personal lab

Log 20 seconds a day. Orrery tests 12 pre-registered claims against your life with calibrated statistics, and "no effect" counts as a real answer.

Private by design

Your chart, journal and lab run on your phone, with an encrypted vault. There's no account needed to read your chart.
