👋 Hey Product Hunt! I'm excited to launch ZenCalcs today! **Why I built this:** I got tired of calculators that required signup just to see a result, showed numbers with zero context, or looked like they were designed in 1999. So I built what I wanted: beautiful calculators that actually explain what your numbers mean. **What's inside:** ✅ BMI Calculator (with weight goals & age/gender inputs) ✅ Mortgage Calculator (full amortization schedules) ✅ Compound Interest (visualize investment growth) ✅ Salary Calculator (convert any time period) Every calculator includes interactive Chart.js visualizations, detailed insights, and comprehensive tables—all mobile-optimized. **Tech stack:** Vanilla JavaScript + Chart.js. No framework bloat, just fast, clean code. The entire site is under 70KB. **What's next:** Planning to add more calculators based on YOUR feedback! What would you like to see? Loan calculator? Tip calculator? Tax calculator? **No catch:** Zero signup, zero ads, completely free. I just wanted to build something useful. Try it: www.zencalcs.com I'll be here all day answering questions and taking feedback! 🚀
