  • Laundry: Washer/Dryer

Steps:
Point at each appliance for 2–3 seconds from multiple angles.

Check:
Are labels correct? Are power values shown?

Test 3: 3D Model Export (Important)

  • Goal: Verify USDZ export.
  • Steps:
    1. Open a scan
    2. Tap Export USDZ
    3. Open the Files app → On My iPhone → S2DT
