The 3D-Scan App allows you to capture 360° images of rooms and spaces. To do this, the app connects via Wi-Fi to the designated hardware (Ricoh Theta, Insta360). Once uploaded to the immersight cloud, the 360° photos can be easily measured in 3D to directly generate a 3D model featuring walls, doors, windows and much more. Exporting as an IFC (BIM) file from the cloud enables the creation of digital 3D twins of rooms, e.g. for quantity surveying, site documentation, 3D walkthroughs or as a virtual showroom.

Verdict

The call

The clearest difference is in-app purchases: 3D at none against Dot3D's 2. 3D also leads on review sentiment (100% vs 81%). Dot3D's advantage is update cadence (every 3 weeks vs every 3 months). On price, ads, device support and iOS requirement there is nothing between them.
