HoraVidya: Kundli & Panchang

ACCURACY
Every chart is drawn from NASA's JPL DE440 ephemeris, the same data professional astronomy relies on, rather than an approximation. The engine is verified against an independent reference across four centuries of dates, with zero rashi and zero nakshatra disagreements.

Twelve ayanamsas are supported, including True Chitra Paksha, Lahiri, Raman, Krishnamurti and Yukteshwar, named as other Jyotisha software names them.

PRIVATE BY DESIGN
HoraVidya has no internet access at all, so your birth details cannot leave your device. No account, no sign-in, no analytics, no ads, no tracking. The only permission it asks for is notifications, for the reminders you set. Place search and every calculation run offline from data bundled in the app.

Planetary positions use NASA JPL DE440 data (public domain). City data is from GeoNames, licensed CC BY 4.0.
