Hey Product Hunt! 👋 I'm a refrigeration technician based in Korea. After years of using HVAC apps that didn't speak my language, didn't work offline, and didn't have AI, I built the one I wanted. R-Pro is for techs who actually work in the field — basements, rooftops, service trucks, equipment rooms with no signal. Not desk managers. What's inside: 🔧 AI diagnosis across 60+ refrigeration fault cases (and growing monthly) 🎤 Voice-to-AI notes — speak it, AI structures it 📷 Scan business cards / equipment nameplates / receipts → fields auto-filled 🧾 Customer + AS + revenue + expense tracking in one place 🌐 10 languages — full translation, RTL Arabic included 📡 Offline-first — works without signal, syncs when reconnected Pricing: $9.99/month · 7-day free trial · 14-day refund · no card friction. If you're a field tech, share what your dream tool would do — I'm building this in public and the next 60 fault cases come from real techs. Thanks for the upvote 🙏
