Construction Calculator

Construction Calculator turns common jobsite measurements into transparent quantity estimates. Use area, volume, slope, flooring, paint, concrete, masonry, mortar, bulk material, rebar, drywall, insulation, tile, paving, decking, fence, stud wall, timber, roof, stairs and spacing tools.

Keep work together in local projects with sections, notes, saved calculation snapshots, costs and jobsite photos. Builder unlocks the practical library and local backup/restore. Pro adds local photo annotation and project PDF report export.

The app is an estimating and planning aid. Supplier product coverage, waste, density and pricing vary. Confirm material specifications and local requirements; the app is not structural engineering, code-compliance, geotechnical or safety advice.

Data is processed on-device by default. Sharing a result/report, exporting a backup, contacting support, or purchasing may transmit the content or transaction information required by that action.
