Mapping a Room with Just Your Phone

Moving into a new apartment and dreading the tape measure? This episode explores whether consumer-grade apps can turn a simple video walkthrough into a dimensionally accurate 3D digital twin. We break down the messy landscape of photogrammetry vs. LiDAR-native apps, explaining why your phone’s sensor matters more than the software. We dive into the critical problem of scale calibration—why a model can look perfect but be completely the wrong size—and compare tools like Polycam, KIRI Engine, Scaniverse, and Apple’s RoomPlan. We also cover the limitations of scanning large spaces, the importance of surface texture, and the specific hardware you need (or don’t need) to make this work. If you’ve ever wondered if you can ditch the tape measure for good, this episode has the answers.
