Using the App

VR Boundary Mode Pro

VR mode lays your property boundary on the real ground using augmented reality. Point the camera at the ground and the app anchors your lines in place — walk around and they stay pinned to the terrain, drawn as a low fence you can see through with a survey stake flagged at each corner.

Pro feature. AR boundary overlay is part of the one-time Pro upgrade — see Free & Pro.

World-anchored, not compass-projected. Earlier the lines were drawn from the compass, so they drifted and swam as you turned. VR mode now uses ARKit world tracking: the boundary is anchored to the real ground and holds its position as you rotate and walk. Compass interference no longer rotates the scene, and ARKit aligns itself to true north automatically.

Anchor your plat first

VR mode requires a GPS anchor at Corner 1. If you haven't set a reference yet, do that first — see Setting a GPS Anchor.

Open VR and scan the ground

From the plat detail view, tap the VR button in the toolbar. Point the camera at the ground and move the phone slowly from side to side — the on-screen prompt guides you. ARKit uses this to detect the ground plane and build a stable world frame. Once it has the ground and a GPS fix, your boundary drops into place on the terrain.

Give it a few seconds. Move the phone gently while it scans; a quick sweep of the ground is enough. If the status reads "tracking is stabilizing," keep moving slowly until it settles.

Walk the boundary

The boundary is now anchored to the ground and stays put as you move and turn. You'll see a low fence tracing each property line, a copper stake standing at every corner with the corner's name flagged at its tip, and the leg distance floating along each segment. Walk the fence line to follow the boundary; the stakes mark where the monuments should be.

It holds its position. Because the scene is anchored in world space, you can rotate the phone or walk around and the fence and stakes stay where they belong — no drift. On a large parcel, ARKit tracks your movement precisely over tens of metres; re-align when you reach a new area (next step).

Re-align from where you're standing

Tap Re-Align VR Overlay to re-drop the whole boundary using your current position. The app captures your GPS and your spot in the AR world at that instant and rebuilds the fence and stakes from there.

Use it when: you first placed the boundary on a shaky fix and now have a steady one; you've walked to a different area of a large parcel; or the lines start to look off after a long session (AR tracking slowly drifts over distance). It does not move your corners or change the plat — it only realigns the AR view.

Re-align on a good fix. Placement is only as accurate as your GPS the moment it drops — so tap Re-Align while standing still with the confidence ring green, the same discipline as anchoring a corner. Under wet or dense tree canopy the fix degrades; do accuracy-critical AR work with a clear sky view.

Accuracy in VR mode

ARKit tracks your movement very precisely, so the boundary stays rock-steady relative to where you anchored it. Its absolute position on the ground is only as good as your GPS fix at the moment you place or re-align — so do that on a steady, high-confidence fix, and re-align as you move across a large parcel. An external Bluetooth GPS receiver helps in open sky; under wet or dense canopy the iPhone's own sensor fusion often holds up better. Unlike the old overlay, compass interference no longer affects the scene.

AR requires a device that supports world tracking (all recent iPhones and iPads). On unsupported hardware the app falls back to a simpler camera overlay.
