Remodel Calculators: Stop guessing. Know exactly how much material you need.

What inspired me: My buddy is a contractor. Every project, he'd spend 10+ minutes manually typing measurements into spreadsheets. Then the client would change one wall, and he'd have to redo everything. I watched him lose hours to data entry. The problem: DIYers guess and buy too much material. Pros re-enter the same numbers over and over. There's no tool that serves both well. How it evolved: I started with free calculators for DIYers (concrete, drywall, flooring). Then contractors kept asking if I could save their inputs. So I built Pro Mode — auto-filling forms that remember your specs. One click, all material lists populated. No more re-typing. I'm launching free for everyone. Pro Mode is cheap enough that if it saves one hour, it's paid for itself. Would love your feedback. What calculators should I add next? 🙏
