Hey Product Hunt! 👋 I'm Paul and I built NumWiz because I was frustrated with math apps for my kid. They were either: ❌ Full of ads ❌ Required sign-ups and subscriptions ❌ Let kids just guess without understanding So I built something different. NumWiz requires children to show their reasoning — not just type the final answer. When dividing 56 ÷ 8, they need to identify that 8 × 7 = 56 first. What's inside: 🧮 All 4 operations: addition, subtraction, multiplication, division 🧠 Step-by-step reasoning required 📱 PWA — works offline, installable on any device 🌍 3 languages: English, Polish, Spanish 🚫 Zero ads, zero tracking, zero sign-up 💰 100% free I also wrote a companion blog with practical guides for parents: 📝 https://numwiz.net/blog/ The guides cover proven methods for teaching times tables, bridging through tens, and division as inverse multiplication — all based on pedagogical research. I'd love your feedback! Especially from parents and educators. What operations or features would you add?
