Astronomy-grade astrology, computed on your device

Starborn astrology tools

Free calculators and readings, all powered by Starborn's own arc-minute-verified ephemeris — the same engine that draws your chart in the app. Every position is computed; every reading is the actual text the app writes.

✦ Computed with Starborn's own ephemeris — the same public-domain astronomical algorithms the app ships (Schlyter for the Sun & Moon), arc-minute verified against a professional ephemeris. No Swiss Ephemeris.

The math is astronomy; the reading is a mirror; what you do with it is yours.
