Aya-Vyaya: Vastu Calculator

Aya-Vyaya is a precise, practitioner-grade calculator for Vastu Shastra and Jyotish, built for professional Vastu Shastris and serious students. It brings the traditional Ayadi Shadvarga Bala calculations — and more — into a clean, fast tool that works entirely offline on your phone.

WHAT'S INSIDE

Vastu Aya-Vyaya (Shadvarga Bala)
• Calculate Aya, Vyaya, Yoni, Nakshatra, Vara, Tithi, Amsha, Dravya and more across three classical methods — Manasara, Vishwakarma Prakash and Aparajita Pruccha.
• Guru, Hasta and Hasta Advanced modes, with floor-based Angula–Hasta conversion (Kishku, Prajapatya, Dhanurmushti variants).
• Custom Hasta length option to scale the Angula to the Yajman's own measured hand.
• Traditional Tarabala for the Nakshatra, and paksha-aware Tithi naming.
• Live results — edit length and breadth and watch every factor update instantly.

Kakini Vichar
• Village and place auspiciousness for a Vastu owner, derived from the first syllable (Avakahada Chakra → Rashi & Varga).
• Recommended build direction, friendly/hostile groups, prohibited direction, Kakini Dhani/Rini, and Dasha Jnana.
• Visual akshara grid and an Ashtavarga direction mandala for quick, tactile selection.

DMS Calculator
• Convert between Degrees·Minutes·Seconds and decimal degrees.
• Add, subtract, multiply and divide angle values, with total-minutes and total-seconds readouts.

BUILT FOR PRACTITIONERS
• Works fully offline — no internet needed, no account, no sign-up.
• English and Marathi (Devanagari) throughout.
• Light and dark themes.
• Clean, distraction-free interface — no ads, no tracking.
• Organise work into projects with multiple plots, homes and rooms.

Whether you are finalising a plot, a home, or a single room, Aya-Vyaya gives you fast, reliable numbers grounded in the classical texts — so you can focus on the reading, not the arithmetic.

Aya-Vyaya respects your privacy: all calculations stay on your device.
