Your elbow is too low. Your toss drifts. ServeFix shows what you can't see — skeleton overlay, your #1 fix, and a drill. Free analysis. No account.
Your elbow is too low at contact. Your toss drifts behind your head. ServeFix sees it — you can't. Record a serve, get your #1 fix and a drill in seconds. No cloud. Video never leaves your phone.
ServeFix analyzes your serve technique in seconds — toss, trophy pose, hip rotation, contact height, knee bend, and stance. Your first analysis is free: see your serve with the skeleton overlay, your #1 mistake to fix, and the one thing you're already doing well. No sensors. 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. Free: your serve video with skeleton overlay, your #1 mistake and its fix, and your #1 strength
4. Pro: the full ranked fix list, a drill for every issue, unlimited re-tests, and your analysis history
WHAT WE CHECK
- Toss placement at trophy
- Elbow height in the trophy pose

Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
Drill animations now show a green wedge for the target angle — toss, trophy position, hip turn, knee bend, contact, and stance. Tap to pause or play.
Skeleton tracking stays smoother through the racket drop and contact, and hip-turn and racket-drop checks are more accurate.
Getting started is shorter. You film your first serve before we mention Pro. Home explains how it works and what we check, with a clear Free vs Pro comparison.
If a clip can’t be analysed, we tell you why and let you record again. A failed clip doesn’t use your free analysis.
