Lidark presents an offline iPhone LiDAR mapping app for recording underground spaces, viewing a live minimap, and retracing a route to the entrance.

Landing page captured for the 2026-10-06 issue.

For: Cavers, mine inspectors, and authorized underground explorers
Worth noticing: The site says the return distance follows the scanned route, with an automatic shortcut if that route forms a loop.

Field notes

The page lays out a three-step workflow: scan while moving, follow a live minimap, then retrace the recorded route to the entrance. It describes saved views as 2D plans, altitude profiles, and a ceiling-removed “dollhouse” 3D view, with PLY and OBJ export for tools including MeshLab, CloudCompare, and Blender. The site says the App Store release is forthcoming; its own copy cautions that the tool is not a safety device.
