ServeFix

Record one tennis serve and get up to 3 clear fixes in seconds — analyzed entirely on your iPhone.

ServeFix uses Apple Vision pose detection to watch your toss, trophy position, hip rotation, contact height, knee bend, and stance. No coach required. No waiting. No sending video to the cloud.

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. Get ranked feedback: issue, fix, and a drill for each mistake
4. Retry, save your clip, or revisit past analyses with Pro

WHAT WE CHECK • Toss placement at trophy • Elbow height in the trophy pose • Hip rotation through contact • Contact height and extension • Knee bend in the loading phase • Stance angle

BUILT FOR PRIVACY • Video stays on your device — never uploaded • No account or sign-in • No analytics or third-party SDKs • Optional: save your clip to Photos

SERVE FIX PRO (OPTIONAL) • Unlimited serve analyses • Full analysis history and comparisons • Personalized drill guidance • Same on-device privacy
