GRIHA VASTU
Griha Vastu is a Vastu analysis app from RetroGrade Arc that reads your real floor plan. Most Vastu tools ask which way your door faces and answer from that alone — but in Vastu, direction is measured from the centre of the home. Griha Vastu works out that centre from the outline of your own walls, then reads every zone from there: the 16-direction grid for rooms and objects, the finer 32-pada ring for your main entrance, and the full 45-devta mandala drawn over your plan.
Griha Vastu is not only a Vastu app. The same account gives you a full numerology reading — core numbers, the Lo Shu grid and mobile numerology — and a Vedic / KP astrology chart with Dasha, Nakshatra, Shadbala and Panchang computed from a JPL-grade ephemeris. Complete Analysis brings all three together in one PDF, including AstroVastu, which maps the afflicted houses in your birth chart onto the directions of your home.
You can start free. Upload a photo of a floor plan, draw the walls yourself, or scan a room in AR on Android — then see every direction's verdict on screen before paying for anything. Griha Vastu runs in any browser and as an Android app on Google Play.
