What you get

🎯

One true centre

Every zone is measured from your home's real centre, computed from the outline you draw — never from where you happen to be standing.

🧭

16 zones and 32 padas

Rooms and objects are read on the 16-direction grid; the main entrance is judged on the finer 32-pada ring, as the doctrine requires.

🛕

The 45-devta mandala

The full Vastu Purusha mandala — 32 outer devtas, 8 inner, 4 corner and Brahma at the centre — drawn over your own plan.

📱

Photo, drawing or AR scan

Upload a floor-plan photo, draw the walls yourself, or walk the room and scan its corners with the Android app.

How it works

  1. Give the outline of your home — photo, drawing, or an AR scan.
  2. Set north with the compass; the app works out the centre and both grids.
  3. Read the verdict room by room, and get the remedies in your report.

What Griha Vastu is

Griha Vastu is a Vastu analysis app built by RetroGrade Arc. It exists because most Vastu tools ask which way a door faces and answer from that alone. Direction in Vastu is measured from the centre of the home, so the app starts by working out that centre from the outline of your walls, then places the chakra there.

From that one centre it draws the 16-direction zone grid used to judge rooms and objects, the 32-pada ring used to judge the main entrance, and the 45-devta mandala of the Vastu Purusha. Verdicts come from an authored knowledge base rather than being generated — each one is a stated rule, not a guess.

The same account also covers numerology and Vedic/KP astrology, and AstroVastu, which maps afflicted houses in your birth chart onto directions in your home. Griha Vastu runs in any browser and as an Android app on Google Play.

Frequently asked questions

Is Griha Vastu the same as RetroGrade Arc?

Griha Vastu is the app; RetroGrade Arc is the company that makes it. On Google Play the developer is listed as RetroGrade Arc.

Do I need an architect's floor plan?

No. A clear photo of a hand drawing works, you can draw the outline in the app, or you can scan the room's corners in AR on Android.

Why does it ask for the direction from the centre?

Because that is how Vastu zones are defined. A compass bearing taken standing at the door tells you which way the door faces, not which zone it occupies.

Is there a free version?

Yes. The 30-second quick check and the on-screen grid reading are free. Paid reports add the full room-by-room analysis, remedies and a PDF.

Which platforms does it run on?

Any modern browser, and Android via Google Play. The AR floor scan is Android-only.
