HMS Scanner

HMS Scanner turns any room into a calibrated floor plan in seconds β€” walls with true dimensions, doors, windows, ceiling heights and detected fixtures β€” using the LiDAR sensor on your iPhone Pro or iPad Pro. The plan travels straight into HMS (Home Management Suite), the platform for home-watch, property-management, inspection and remodeling pros β€” no files, no manual steps. WHAT YOU CAN DO β€’ Scan a home into a measured floor plan with room zones and real square footage. β€’ Run WiFi, noise and light surveys β€” walk the home and get heat maps over the plan, each with a branded PDF report. (NEW) β€’ Capture multi-story homes floor by floor in one session. (NEW) β€’ Use the precision bubble level for shelves, frames and fixtures. (NEW) β€’ Get quantity takeoffs (paint, baseboard, trim, ceilings, floors) and build quotes β€” no tape measure. HOW IT WORKS β€’ Open the scanner from HMS in Safari, or launch the app directly. β€’ Walk the room pointing the camera at the walls. β€’ Name the room and tap "Send to HMS" β€” your plan opens already drawn. β€’ Or export the survey as JSON, or share the 3D model (USDZ) via AirDrop. BILLABLE MEASUREMENTS, NOT GUESSES RoomPlan delivers true metric dimensions β€” wall heights, door and window widths, per-element confidence. HMS turns them into zones, takeoffs and quotes for real work. REQUIREMENTS β€’ iPhone Pro or iPad Pro with a LiDAR sensor (iOS 17 or later). β€’ An HMS account to receive plans (scanning and file export work without an account). PRIVACY HMS Scanner collects no personal data. Scans are processed on-device and sent only to your own HMS account, when you choose to.
