Hey Product Hunt! 👋 I built Calculator Pro out of frustration. Every time I needed a quick calculation I'd land on calculator.net or similar sites — buried under ads, slow to load, with the actual calculator hidden below 3 paragraphs of SEO filler. I wanted something clean and fast where you just... calculate. Started with the basics, then kept going. Now at 200+ calculators: finance depth (IRR, debt snowball, HELOC, RMD), full health & fitness suite, math, science, and 150+ unit converters with smart badges so you always know exactly what units you're converting. All free, no account required, mobile-friendly. Would love feedback — what calculator do you wish existed that isn't here yet? 🙏
