Hey Product Hunt! 👋 Built CalcFlip in 20 days — 23,000 pages across 4 languages, each with unique structured data, FAQ schema, and full AEO optimization. The idea was simple: every single time conversion, Roman numeral, and temperature query deserves its own clean, fast, ad-free page. Would love your feedback on what converters to add next — height/weight and fractions are coming. Check it out at calcflip.com 🙏
