Room Twin

Architects, designers and educators constantly need a quick, accurate 3D record of a space — but traditional capture means specialist scanners, tripods and software. Most people just want to point their phone and get a model.

The challenge: make spatial capture effortless enough for anyone, while keeping the output accurate and genuinely useful downstream.

Room Twin leans on the LiDAR sensor already in modern iPhones and iPads. You walk the space, and a clean 3D model forms in real time — walls, doors, windows and furniture snapping into place as you go.

Export is deliberately focused: a single, portable USDZ that opens anywhere in the Apple ecosystem.

The hardest design work was hiding the complexity. Scanning guidance, live feedback and a calm editing view let first-time users get a usable model on their very first try — no manual required.

Later updates added custom 3D props (a TV, a sofa) and floor-plan export as a JPG, growing the app around how people actually use it.

Built in SwiftUI on Apple's RoomPlan and ARKit, Room Twin processes the LiDAR point cloud into structured geometry on device, then exports clean USDZ ready for AR Quick Look, design software or a presentation.

Room Twin is live on the App Store — free, rated 4.8★, and built for iPad with full iPhone support. It's become a quick, reliable way to turn a real room into something you can share, present and build on.

Room Twin is part of a bigger belief: that spatial capture shouldn't be locked behind expensive gear. When anyone can scan their world in seconds, whole new kinds of learning, design and storytelling open up.
