About this app

PerunTeCH Astro is a calculation instrument, not a fortune teller.

Enter a birth moment — the wall-clock time, and the town or village you
were born in — and the engine computes the traditional structure from
first principles: the sidereal positions of all nine grahas, your
nakshatra and pada, the rising sign, and the running Vimshottari stack,
laid out as a live instrument you can read at a glance.

**The whole chart, free.** Rashi (D-1) and Navamsa (D-9), every graha
placed with its nakshatra, pada and classical dignity, the traditional
yoga and dosha configurations, and a live Sade-sati reading. Not a
preview, not a teaser — the classical read, in full.

**Your birthplace, by name.** Type the town or village. Over five million
populated places are built into the app — village level, every country —
so you never have to look up coordinates or know which timezone database
entry applies. The place supplies its own latitude, longitude and the
offset that was really in force on the day you were born, including
historical and wartime shifts.

**Explainable by design.** Every number traces to published astronomical
algorithms — a VSOP87D-based ephemeris verified against NASA JPL Horizons,
Lahiri ayanamsa. Same input, same wheel, every time. No black boxes.

**Private by design.** Everything computes on your device, including the
place lookup — nothing is searched online. Your birth data never leaves
your phone: no account, no upload, no tracking.

**An instrument, not an oracle.** We show you the traditional structure
of time with engineering honesty. What it means to you stays yours.

Built with respect for the tradition by PerunTeCH.
