A PRACTICAL WORKFLOW
Plan before you shop
- Choose your project type and enter your measurements.
- Enter the relevant material coverage, packaging and prices.
- Review the material list against supplier information before buying.
Use metric or US customary units and EUR or USD for each project. Estimates depend on the measurements, material information and prices you enter.
One app. Choose the tools you need.
Both audience pages lead to the same KlusSom iPhone app. The professional workflow uses optional KlusSom Pro features.
Do I need Pro for a home project?
Material calculations, material costs and saved projects are free. Pro is optional and adds business pricing, quote versions and PDF export.
Where are my projects stored?
Projects are stored locally on your device. Calculations work offline; buying or restoring Pro requires an App Store connection. See KlusSom privacy.
What should I check before using an estimate?
Verify measurements, supplier packaging, material requirements, prices and applicable tax rules before ordering or issuing a quote. Tax rates are entered manually; KlusSom does not look up local tax rules.
