## What is Blueprint SpeedSketch?

LiDAR scan + manual or Bluetooth laser distance meter calibration + one-tap export to DXF / PDF / SVG / PNG.

For interior designers who want to sketch on-site and stop redrawing back at the office.

[Workflow]
• Start scan — walk around with iPhone Pro LiDAR
• Done — calibration screen with floor plan
• Tap any wall / door / window — manual entry or BLE auto-fill from Bosch GLM laser meter
• Export — DXF for AutoCAD/SketchUp/Rhino, PDF for client proposals, SVG vector, PNG for messaging

[Highlights]
• Fully offline, no ads, no IAP, one-time purchase
• Mung bean green theme (#C7EDCC), easy on the eyes
• Floor plan synced with row list — never confuse which wall you are editing
• Supports Bosch GLM laser meters via BLE (manual entry always available)

[Requirements]
• iPhone 12 Pro series or later (LiDAR sensor required)
• Standard iPhone and SE not supported

[Known Limits]
• RoomPlan accuracy ±5cm; custom builds still require physical tape verification
• Best with one room at a time
