Create and save projects, enter measurements, allow for openings and waste, calculate material quantities and estimate material costs. Keep your work on your iPhone and return to it later.
FIVE PROJECT CALCULATORS
• Paving: surface area, paver packages, foundation and bedding, waste allowances and ordering in whole purchase units.
• Painting: walls, ceilings, openings, coats, coverage and paint packages.
• Flooring and trim: floor areas, cutouts, material packages, underlay and trim.
• Tiling: floor and wall areas, tile boxes, adhesive, grout and waste.
• Plastering: surface areas, thickness, material use and supplies.
US UNITS AND USD
Choose US customary or metric units and USD or EUR for each project. Work with feet, square feet, inches, cubic yards and US gallons where applicable. The interface is available in English and Dutch.
KLUSSOM PRO — ONE-TIME PURCHASE
Unlock customer pricing, quotes and PDF export with one non-consumable in-app purchase. No subscription. The App Store price is shown before you buy, and Restore Purchases is available in the app.
With Pro you can:
• Add labor, transport and other project costs.
• Calculate customer prices and profit margins.
• Enter a manual tax rate for US projects.
• Create quote versions and share a professional PDF.
• Reuse material and price profiles for paving projects. Changing a profile does not change existing projects or saved quotes.
Paving projects also support a manual tax base and show tax and the total on the quote. Tax rates and taxability are entered by you; KlusSom does not look up local tax rules.
PRIVATE AND PRACTICAL
No account, ads or tracking. Projects, prices and customer details are stored locally on your device. Calculations work offline; buying and restoring Pro requires an App Store connection. You choose when and where to share a PDF.
KlusSom provides estimates. Check measurements, supplier packaging, material requirements, prices and applicable tax rules before ordering or issuing a quote.
