Quick Look is part of iOS and iPadOS (15 or later for current experiences). When a WebAR link points to a USDZ file, Safari opens it directly in Quick Look.
On LiDAR-equipped Pro devices placement is almost instant; on other iPhones the device scans the floor for a few seconds first. Thridify exports each product as USDZ automatically for this path.
Why it matters
Quick Look is why app-free AR works on every modern iPhone: the viewer is already installed on the device.
