Construction Field Calculator for iPhone

Terms of Use

Last updated: November 7, 2026

Construction Field Calculator is provided by Dzmitry Dziachenka. This page identifies the applicable license and explains the product. It does not replace or modify Apple’s agreement.

1. License

The app is licensed under Apple’s Standard End User License Agreement (EULA).

2. Estimates and limits

Results are quantity and geometry estimates based on your inputs and the disclosed formulas, waste, rounding and pricing assumptions. They are not structural engineering, building-code approval, a safety assessment or a supplier quote. Check site measurements, product instructions and local requirements before using an estimate to order materials or build.

3. Free features and Pro Lifetime

Concrete, area, dimensional math and conversion are free, with three active jobs and unlimited records within each. Pro Lifetime is one non-consumable in-app purchase, with no subscription or recurring charge. It adds eight specialist calculators, unlimited jobs, PDF and CSV field reports, and custom material presets. The current localized price is shown in the app before purchase. Family Sharing is not enabled for Pro.

Use Restore Purchases with the Apple Account used to buy Pro. Apple handles payments and refund requests. If verified Pro access is lost, existing records stay readable and JSON backup stays free; paid operations are locked. Deleting local work does not cancel or refund a purchase.

4. Privacy and support

See the Privacy Policy for local storage, backups, exports and support-email handling. Support offers help with the app, calculations, imports and purchases, with no guaranteed response time or engineering certification.

5. Changes

Product information on this page may be updated as the app changes. The linked Apple Standard EULA governs the license.
