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.
