SurfacePro - Area Caculator

Measure any surface area with your iPhone camera (AR with LiDAR) or GPS — indoors or outdoors, small rooms or large fields. SurfacePro gives you professional area, perimeter, and terrain readings in seconds.

TWO WAYS TO MEASURE

AR Mode — Point your camera at any surface, tap to place points, and close the shape. Get instant area and perimeter. Works on floors, walls, yards, patios, and roofs. Enhanced accuracy with LiDAR, but works on any iPhone.

GPS Mode — Two input methods:
• Live GPS — Walk the perimeter and drop pins at each corner. See your polygon on a satellite map with real-time area, slope, and elevation.
• Pin Placement — Tap anywhere on the satellite map to place points. Drag pins to fine-tune with a magnifier loupe for pixel-perfect positioning. Ideal for remote areas or planning from your desk.

MEASURE MULTIPLE SURFACES

Add multiple polygons in a single session. Completed shapes stay visible on the map while you measure the next one. Get distance analysis between polygons — perfect for calculating gaps, setbacks, or spacing.

FEATURES

- Real-time area and perimeter as you build your shape
- Up to 100 measurement points per polygon
- Distance labels between GPS points on the map
- Point counter showing current vs. maximum points
- Metric (m², cm) and Imperial (ft², in) units
- GPS area in m², hectares, or acres
- Save unlimited measurements with location tagging
- Search, filter by mode, and view all saves on a map
- Adjustable polygon opacity and line styles (solid, dashed, dotted)
- Organise measurements into folders
- Annotate diagrams resulting from AR or GPS measurements and export in PDF

PROFESSIONAL EXPORT

- PDF reports with shape diagrams, compass indicator, dimensions, and optional AR screenshots
- GPS reports include satellite map overlay showing your polygons
- KML files for Google Earth and GIS software
- GPX files for mapping applications
- CSV export with point coordinates and accuracy data
- Share GPS measurements as map links

DIAGRAM ANNOTATIONS

Add text labels, arrows, circles, rectangles, and hatch fill patterns to your measurement diagrams. Move, resize, and rotate any annotation with full color customization and 30-level undo.

GPS TERRAIN ANALYSIS

- Min/max altitude and elevation change
- Average and maximum slope (degrees and percent)
- Real-time GPS accuracy monitoring
- Barometric altitude for precise elevation data

WORKS WITHOUT LIDAR

SurfacePro uses a 3-layer accuracy system: LiDAR mesh detection, plane geometry, and estimated planes. Any iPhone with ARKit can measure surfaces — LiDAR simply gives better results on uneven terrain.

PRIVACY FIRST

All data stays on your device. No accounts, no analytics, no tracking, no ads. Your measurements never leave your phone.
