Hey Product Hunt! 👋 I'm Zakaria, and I built Kairox because I was tired of running apps that showed me everything but told me nothing. I had a GPS watch, Strava, and two years of data but I still didn't know if I was training right, recovering enough, or actually improving. So I built Kairox: a running app that doesn't just track your runs, it coaches you after every single one. Here's what makes it different: 🤖 AI Run Analysis: after every run, you get plain-language recommendations based on YOUR data. Not generic tips. Actual insights like "you started 30s too fast — here's how to fix it." 📊 Advanced Analytics: pace trends, effort evolution, heart rate zones, weekly load analysis. 🎯 Race Prep Plans: tell us your race date and goal time. We build a week-by-week plan tailored to your current fitness. ❤️ Heart Rate Zone Breakdown: see exactly how much time you spent in recovery, aerobic, tempo, threshold, and max zones. 🏆 Founding Member spots: we have 100 spots for early believers who want to help shape the product and lock in their price forever. I built this solo, launched it in Belgium, and I'm here all day to answer every question. What's your biggest frustration with running apps right now? Let me know below 👇
