House Call
Multi-tradition natal-reading practice. Hand-prepared readings synthesise Western, Chinese BaZi, and Vedic Jyotish, backed by per-user accounts, daily astronomy-engine transits, a falsifiable prediction tracker, synastry, palmistry, and tarot import. A free chart snapshot is open to anyone; the full reading is by application.

01Discover
Why it exists.
Most natal-chart software treats traditions as separate islands - pick Western, Vedic, or BaZi, and stay in it. Practitioners who synthesise across traditions in practice have nowhere to host that synthesis as a product.
House Call is that host. Hand-prepared readings that braid Western (Vronsky lineage), Chinese BaZi, and Vedic Jyotish into one document, with real product infrastructure underneath it rather than a one-off PDF.
02Define
The brief.
Host a three-tradition natal-reading practice that scales by depth, not sign-up volume, with intimacy and per-user privacy as preconditions.

What shipped.
Live at housecallastro.com. The free chart snapshot is open sign-up, the full multi-tradition reading is by application, and Stripe checkout is built but gated off behind an env flag until the founders' cohort closes.
Live since May 2026 - gating keeps per-reading depth intact as the cohort grows.
