DEUCE - Track tennis. Challenge friends. Win. 🎾

Hey Product Hunt! 👋 I'm Paco, a young French developer and tennis player. I built Deuce because I couldn't find a simple app to track my matches and compete with friends. So I coded it myself — solo, from scratch. Deuce lets you: 🎾 Track live scores (sets, games, points) 🏆 Create mini-championships with friends 📊 ELO ranking that evolves after each match 🥇 Unlock 24 badges based on your performance 📱 Install it like a native app (PWA) — no store needed Would love your feedback! Happy to answer any questions 🙌
