iPhone LiDAR vs Traditional 3D Scanners: What the Specs Leave Out
How iPhone LiDAR compares to handheld structured-light, consumer desktop, handheld SLAM, and photogrammetry scanners - why the stated accuracy figures are not comparable, and what the peer-reviewed head-to-head studies actually measured.

LiDAR + LLMs: Scan-to-Report Is the Next Enterprise Mobile Feature
Scan-to-report pairs mobile LiDAR capture with a language model so a spatial scan comes out as a finished deliverable - a claim narrative, an inspection report, a maintenance checklist. No iOS category leader owns the pattern yet. Here is the architecture, the on-device question, and who should build it.
