Sweep: 2D/3D Instant Floorplan

Sweep turns your iPhone's LiDAR scanner into a professional floor-plan tool. Walk through a space, and Sweep builds an accurate 2D floor plan and 3D model as you go — no measuring tape, no CAD software, no guesswork. Scan a room, then the next, and the next Sweep tracks doorways as you walk between rooms and snaps them together automatically, so a multi-room scan reads as one connected floor plan instead of a pile of disconnected shapes. A live quality score coaches you toward a complete, accurate scan — full coverage, steady movement, the right distance from the walls — so you know before you finish whether it's good enough to hand to a client. Fix mistakes without rescanning LiDAR occasionally misreads a mirror as a wall, or a built-in as a doorway. Sweep's floor plan editor lets you correct it directly: drag a corner into place, relabel an opening, remove a phantom wall — all without walking the room again.
