+- **First real tester:** a 65-year-old with low vision used the app on the author's iPhone and said that after a couple of runs he could guide himself through the rooms and find his wallet. One person's account, not a measured study.
 - **Reconstruction speed (M5 Pro, Apple GPU):** one room, 63 frames from a 21-second phone video, MapAnything with the Apache-2.0 weights: **19.6 s** of inference, **14.8 GB** peak memory, 11.3 s to load the model.
 - **Scale, images only:** two tape-measured desks (78 cm and 61 cm) came out about **23 % too large**, both by the same factor, so the shape is right and the absolute scale is not. This is why the pipeline feeds the phone's depth and poses into MapAnything. The tape-measured 20 cm check with the phone's inputs is still open.
 - **Room processing:** **60 s** per room with the warm model server (143 s before it), on the M5 Pro.
