ServeFix: Tennis Serve Coach

Fix your tennis serve with AI. Prop your phone. Hit record. Fix your serve. ServeFix analyzes your serve technique in seconds — toss, trophy pose, hip rotation, contact height, knee bend, and stance. Get clear, ranked fixes you can use on your next serve. No subscription. No sensors. No cloud. Built for players who practice alone and want real feedback without a $30/month subscription or a court-mounted camera. WHY SERVEFIX Most tennis apps either measure serve speed or record full matches. ServeFix does something different: it breaks down your serve technique and tells you what to fix. It's a serve coach in your pocket — not a radar gun, not a match tracker. HOW IT WORKS 1. Record a serve or upload from your library (3-15 seconds) 2. Stand side-on so your full body is visible 3.
