Material Cost Calculator is a construction material estimation tool that helps users calculate quantities and costs for lumber, concrete, drywall, flooring, and other building materials. The App is provided as a planning aid only.

3. Disclaimer of Accuracy

IMPORTANT: Material Cost Calculator provides estimates only. All calculations are approximate and intended for planning purposes. Actual material requirements may vary based on site conditions, material availability, waste, cutting patterns, and other factors. You should always consult with a qualified contractor or building professional before purchasing materials or beginning construction. We are not responsible for material shortages, overages, or costs resulting from reliance on the App's estimates.

4. In-App Purchases

The App offers a Pro upgrade as a one-time, non-consumable in-app purchase ($4.99 USD or local equivalent) that removes ads and enables CloudKit sync. All purchases are processed through Apple's App Store and are subject to Apple's terms and conditions. Refund requests must be directed to Apple.
