## What is Clay Tennis?

Clay turns your iPhone into an intelligent tennis coach.
Record your serve, upload the video, and Clay uses on-device AI to measure your serve speed directly from ball trajectory — automatically counting serves and highlighting your best ones.
But Clay goes far beyond speed. With the AI Coach, your serve technique is analyzed frame by frame. The app detects key positions like the trophy pose and contact point, then delivers clear, actionable feedback to help you fix mistakes and improve faster.
Every analyzed serve is saved in a clean, visual feed. Compare sessions over time, track your progress, review technique insights, and see your fastest serves at a glance — all organized and easy to revisit.
Learning continues off the court with interactive quizzes and short lessons designed by tennis experts. Build a more consistent, powerful serve by mastering the fundamentals step by step.
A built-in recording guide shows you exactly how to position your phone for accurate results. All analysis runs entirely on your iPhone — your videos stay private and never leave your device.
Train smarter. Serve faster. Improve with Clay.
