How the numbers are made

Planet positions come from Astronomy Engine, an open MIT-licensed ephemeris. The Ascendant and houses come from the local sidereal time and latitude. The reading is assembled from a written library, not generated by a model.

What is free

Every calculation, every sign page and every pair page is free: your signs, your big three on the wheel and your Saturn return dates. What each placement means for you, the aspects and the full chart are in the reports. Saving a chart needs an account so it can follow you to another device.

What this is not
