A birth chart, read properly

What it is

Most astrology apps are templates: a handful of prewritten paragraphs, selected by sun sign. The maths is approximate and the words are the same for millions of people.

Lumi takes the opposite approach — get the astronomy exactly right, then write against what the chart actually says.

How it is built

Observatory-grade chart maths

Positions come from Swiss Ephemeris, the same ephemeris serious astronomical software uses, calculated from full birth details rather than a date alone.

A reading per person, not per sign

The model is given the computed chart and writes to it, so two people born the same day in different places get different readings — which is the whole premise, and what a template cannot do.

A freemium line that is actually a line

The free tier gives a complete, useful result — the Big Three — and the paid tier is the full reading. Free is not a teaser with the answer removed.

Our own software, not a client engagement. There are no business figures attached to it and none are claimed — the point of the link above is that you can check the work yourself.
