focalScan
Square Footage Calculator for Paint, Flooring, Trim & Wallpaper.

focalScan is a room measure app that uses iPhone LiDAR to scan a room and create accurate room measurements—then converts them into purchase-ready totals with a paint calculator, flooring calculator, and wallpaper calculator / wallpaper estimator. Review the model, confirm dimensions, then export a PDF or share the project.

Scan on site with iPhone LiDAR—fast room measurement

focalScan turns your iPhone's LiDAR into a practical measurement tool. Capture the space once and the app builds a live 3D model that adapts to irregular layouts, angled walls, and vaulted or sloped ceilings. Doors, windows, and openings are detected automatically so your totals reflect the surfaces you'll actually coat, cover, or trim.

  • Fast LiDAR-based room measurement
  • Detects doors, windows, and openings automatically
  • Works with irregular rooms and vaulted/sloped ceilings
  • Voice-enabled for hands-free use

Review measurements in 3D + 2D floor plan

After capturing, inspect the room as an interactive model or a flat floor plan. Rotate, zoom, and verify every dimension before converting them into material quantities.

  • Wall surface area — for coatings and decorative finishes
  • Floor area — total room area for hard and soft surfaces
  • Room perimeter — baseboard, casing, and millwork runs
  • Ceiling height — accurate surface totals for tall or angled rooms

Turn verified dimensions into order-ready quantities

focalScan converts confirmed measurements into clear buying totals for weekend projects and professional estimates alike.

  • Paint — Determine how many gallons you need based on wall area, spread rate, and number of coats
  • Flooring — Room area with overage factors for hardwood, tile, LVP, and carpet installs
  • Tile — Surface area with cut allowances for layout patterns and edge waste
  • Wall Covering — Roll counts with pattern repeat support including straight match, drop match, and random match
  • Trim & Millwork — Baseboard, crown, and chair rail totals with door deductions and piece counts

focalScan AI Pro Assistant

Estimating materials involves more than dimensions—coverage rates, coats, overage factors, and pattern alignment all play a role. The AI Pro Assistant helps you validate decisions by text or voice, using your room data as context.

  • Overage and waste guidance by material type
  • Spread rate and coat recommendations for coatings and primers
  • Pattern repeat and alignment advice for decorative wall finishes
  • Deduction logic for doorways, windows, and openings

Capture once. Share with painters, installers, and designers.

Built for DIY homeowners, home decorators, remodelers, handymen, painters, and wall covering installers. Also ideal for interior designers who want to capture a space and share it with a tradesperson or project team.

Map the room once, then keep everyone aligned with the same model, views, and dimensions. Share by PDF export or project file (when collaborators use focalScan). Fully localized in 16 languages with imperial and metric units.
