Hey Product Hunt! 👋 I'm a mechanical engineer who got tired of BMI calling me "overweight" despite being a fitness professional. BMI is fundamentally broken - it can't tell the difference between muscle and fat. So I built BC Calculator. ** The Problem ** BMI only looks at height and weight. A muscular athlete and someone who's genuinely unfit can have the same BMI. It labels bodybuilders as "obese" and skinny-fat people as "healthy." ** The Solution ** BC Calculator uses body composition - your actual body dimensions plus weight - to give you a true 0-100 fitness score. It's based on biomechanics principles, not outdated height/weight ratios. ** How It Works ** - Enter height, weight, gender (10 seconds) - Use your phone camera to measure body widths with a credit card for scale - Get your real fitness score (0-100) with detailed interpretation Takes under 60 seconds total. No gym visits, no expensive DEXA scans, no inconsistent caliper tests. The core app is 100% free, works offline, and your data stays completely private on your device. 🎉 **PRODUCT HUNT EXCLUSIVE** 🎉 Use code **PRODUCTHUNT60** for 60 days of BC Calculator Pro FREE! Unlock unlimited history, advanced charts, progress analytics, and measurement notes. I'd love your feedback! Especially from athletes, biohackers, or anyone else frustrated with BMI. What do you currently use to track body composition? Available on Android now, iOS coming soon.
