Heatpunk turns your iPhone or iPad into a fast, accurate survey tool for heat pump design. Walk through each room and scan it with Apple's LiDAR-powered RoomPlan, or measure it with AR Measure on any iPhone.

SCAN • LiDAR room scanning: capture a room in minutes, floor to ceiling • AR Measure on any iPhone: tap the corners of the room with the camera • Tap a radiator during the scan to measure it and place it on its wall • Hold Note during a scan to record a voice note for that room • Multi-room and multi-floor surveys, with floors lined up by dragging PLAN • Automatic 2D floor plans: walls, doors, windows and room shapes • Smart room tagging suggests room types from what the scan finds • Edit room names, types, notes and sizes • Square up a room that is a few degrees out • 3D model view and sharing SURVEY • Set building materials for the whole house, then change any single wall, window or door • Choose from Heatpunk's eight radiator types • Answer the Heatpunk survey questions on site and add photos SEND • Connect to Heatpunk by scanning a QR code.
